Restoring these areas with a fiberglass repair kit is cost-effective and far less time consuming than cutting out and welding new metal panels. A few simple tools and a little patience make the process a snap. Keep reading the article below to learn more about Fiberglass Auto Body Repair.

The car body on your classic Elise or Exige is made of fiberglass, and that material is not immune to the same kinds of abuse that metal-bodied vehicles experience. Whether someone backs into your car at the grocery store or you have a few star cracks on the rear quarter panel, you need to get those damaged areas repaired as soon as possible. A trip to the auto body shop isn’t necessary to do so; a few simple tools and a little bit of time will allow you to repair your fiberglass body panels with relative ease.

Before you start repairing the damage, though, it’s important to properly prep the area that you are attempting to restore. This includes sanding down the paint with a dual-action sander to remove it, and then using a coarser grit sandpaper to make sure that all of the old paint is removed. This will help ensure that the new fiberglass will adhere to it correctly.

After that, you need to make sure the area is cleaned thoroughly using a low-VOC compliant cleaner and then sanded again. You also want to sand down the edges of the damaged area 1″ beyond the edge of the actual repair to roughen the surface and ensure that it will hold the new fiberglass.

Once the area is ready to receive a new coat of fiberglass, you need to mix the resin and cloth that will make up the new repair. The best fiberglass resin to use is polyester resin, which is easy to work with and dries quickly. Once the resin is mixed, you can then cut the fiberglass cloth to size and apply it to the damaged area.

Prepping the Surface

After the fiberglass has been sanded down and any repairs made, it is time to prime. The body must be thoroughly cleaned before applying primer to ensure that the surface will adhere. This can be done using Eastwood PRE Painting Prep #10041Z. This aerosol product is sprayed on and wiped off with a clean cloth. It is important that the degreaser be allowed to dry for an hour or so.

After priming, it is a good idea to sand the entire body once again. This will provide a smoother finish and allow any rough areas to be smoothed out. If the fiberglass is not sanded properly it may be possible to see through the paint.

A sanding block and 80-grit sandpaper work well for this step. Then, it is time to use some standard car body filler or glazing putty to smooth out low spots on the fiberglass. This is also a good time to fill any pinholes. Be careful when you do this; you dont want to force any epoxy into these holes. The best option is to use a finer grit sandpaper (180 or 220-grit) to smooth the body filler.

The next step is to sand the area again and make sure that it is smooth and free of contaminants. Then, it is a good idea to apply another coat of primer. Be sure to follow the manufacturers recommendations regarding primers. It is also a good idea to check compatibility with the paint that you are planning on using.

When it is time to add the fiberglass patch, you will need to cut some glass cloth. You can do this with a utility knife. Then, you can cut a few plies of fiberglass cloth, each one smaller than the last. You will need enough layers to fill the damaged area. You can use a variety of fiberglass cloths; however, Marsons Marglass or Evercoat Kitty Hair are both great options.

Mixing the Resin

Fiberglass is a strong, lightweight material that’s commonly used in car body construction. It consists of thin strands of spun glass that are combined with a resin, and it’s often molded into complex shapes to form an aerodynamically efficient vehicle body. However, just like metal or plastic, fiberglass is prone to damage and requires special care to maintain its structural integrity.

The first step is to mix the epoxy resin and hardener. The general rule of thumb is to use two parts resin and one part hardener, but this can vary from product to product so it’s important to read the instructions on the product label carefully.

Once you’ve figured out how much resin you need, pour it into a mixing container and add the hardener. Then stir the mixture for 2-4 minutes, scraping the sides and bottom of the container to make sure that nothing is stuck. This will help ensure that the mixture is fully mixed and ready to use.

As you stir, be careful not to introduce air bubbles into the resin. Air bubbles can weaken the bond between the fiberglass and the coating. The best way to avoid them is to work slowly and to stir the resin over something that doesn’t absorb it, such as a piece of cardboard or wax paper.

After the resin is fully mixed, it’s time to apply it to the automobile. Be sure to wear rubber gloves and safety goggles, as working with fiberglass can be messy. The resin will start dripping almost immediately, so cover anything nearby to contain the mess and protect any surfaces you don’t want to get wet. If necessary, you can also use a mask to reduce the risk of breathing in the resin vapors.

Applying the Resin and Cloth

Fiberglass is a versatile material that can be used to repair any type of damage on a car. Whether it’s star cracks, extra holes drilled for no apparent reason or accident damage, fiberglass can make the repaired area stronger than the original part. While working with fiberglass, it is important to follow certain steps to ensure a strong and long-lasting repair.

Before applying the resin and cloth, it’s a good idea to sand the entire area around the damaged site. This will create a clean, smooth surface that will allow the new layer of fiberglass to bond properly with the existing area. A sanding tool with coarse-grain sandpaper should be used to achieve the desired results. After sanding, the area should be cleaned using a rag and acetone to remove any oil or dust that may prevent the fiberglass from adhering to the surface.

The next step is to mix the resin. Pour the desired amount of resin into a bucket and add the hardener according to the proportions indicated on the container. Be sure to wear latex gloves while mixing the materials to avoid contaminating the remainder of the container with any contaminants. It’s also a good idea to work in a well-ventilated area and use a respirator mask when working with the resin mixture.

Apply the resin to the sanded area and then place a piece of fiberglass cloth over it. Saturate the cloth with resin, then begin to wrap it around the damaged area. Continue this process until the whole damaged area is completely covered with a layer of fiberglass. Let the resin dry for a day. This will give the resin enough time to fully cure.

Finishing the Repair

When the fiberglass resin cures, it creates a tough and durable material. It can withstand impact damage, and it is also easy to work with. This makes it an ideal material for auto body repair and restoration. In fact, some auto service technicians specialize in repairing cars with fiberglass bodies. Having this type of skill can be a huge advantage for career advancement.

To make a fiberglass repair, the damaged area is cleaned thoroughly using acetone or contact cleaner. Then the surface is roughed up with sandpaper (typically 280 grit). This prepares the fiberglass for bonding. If necessary, a form can be used to shape the repaired surface. For small holes, a rubber spreading card is often sufficient to fill the hole. The resulting surface is then sanded until it blends smoothly with the surrounding undamaged area. Once the sanding is done, a polyester body filler called Bondo can be applied.

A thin coat of gelcoat is then applied to the fiberglass. This is a thicker substance than paint and requires a special spray gun, but many automotive enthusiasts can do this at home. It is important to apply this coat to a clean surface, since any fingerprint or smudge of oil will show up as spots or fisheyes in the final finish.

Fiberglass is an adamant material, but it can still crack and chip if exposed to harsh conditions or an accident. This is why it is so important to learn how to repair fiberglass components. With the proper tools and materials, a DIY fiberglass repair can be done by anyone with a little practice. This is one of the many skills that are taught during trades training to help students make the transition from student to professional.

Tips For Motorcycle Detailing

by Posted in Auto Services Tagged , , , , , , , ,

Motorcycles have a variety of upholstery, including coated leather and high-quality vinyl that feels like leather. These materials require special cleaners and protectants.

Motorcycle Detailing

Motorbikes also have chrome parts that should be polished to a shine. Keeping the bike clean not only improves its appearance but also makes mechanical problems easier to spot. Contact Motorcycle Detailing Perth for professional help.

A motorcycle’s paint and chrome are highly exposed, so they can be especially vulnerable to oxidation and corrosion. This is why it’s important to wash and rinse them frequently. This will help the bike look better and also keep it safe to ride.

Start by rinsing the entire vehicle with a garden hose or even just a bucket of water. This gets off the large pieces of dirt, and it prevents them from scratching your paint when you wipe it down with a cloth or sponge.

During this step, you’ll want to pay special attention to the leading edges of your controls and other components that face forward. They’ll likely have more bugs and grime on them than other areas of the bike. It’s a good idea to rinse your brush or sponge out often, too, as you go. This helps avoid transferring dirt from the dirty parts of the bike to the clean ones.

The next step is to clean the bike using a mild soap, either a liquid bike-wash soap or a gentle dish washing detergent. Don’t use harsh household cleaners as they can strip the wax coating on your bike and cause damage to its paint. You’ll need to rinse the soap thoroughly, too, and you may want to use a second bucket of water for this purpose.

Once the bike is thoroughly cleaned, it’s time to dry it. The first thing you’ll need to do is remove the spark plugs and the oil filter. You’ll want to take special care around the battery and any electrical connections, as they’ll be very sensitive to water.

You’ll also want to cover the radiator, as any acid that gets into it can damage the paint and the metal. Finally, you’ll need to reinstall the side covers, saddlebags and any other bodywork that was removed during the cleaning process.

Degrease

Even if you have taken the time to wash your motorcycle with soap and water, there is still likely dirt and grime that has bonded to the surface of the paint. This is why it is important to degrease your bike after you wash it.

Using the degreaser that is recommended for your motorcycle, spray it liberally over the areas with a bad buildup of grease and oil. Give the degreaser a few minutes to work and then use your scrub brush and a little elbow grease to get those hard-to-reach areas. When you are done, rinse and dry thoroughly with a microfiber towel.

After you have rinsed and dried your motorcycle, it is a good idea to protect its rubber components with a high quality rubber protectant to help keep the sun from damaging them. This is particularly true on the seat and any other areas where the bike will be parked outdoors, like the fenders. A motorcycle cleaner with built in UV protection will help to keep the rubber components in good condition.

It is a good idea to use a cleaner that also provides UV protection for the dash of your motorcycle as well. Keeping this area clean will not only make your motorcycle look better, but it will also help to prevent the cracking and discoloration that can occur over time.

One of the biggest advantages of detailing your motorcycle regularly is that it can help to increase its resale value. Potential buyers will be more likely to pay top dollar for a clean, shiny motorcycle that is in good working condition.

Taking the time to clean your motorcycle can make it easier and more fun to ride. Plus, it will help to protect your investment and extend the life of your motorcycle. So if you haven’t done so lately, take the time to wash your motorcycle and degrease it, then polish it up and protect it with a coat of protective wax. It will be well worth the effort.

Polish

The paintwork of a motorcycle is more fragile than that of a car. That’s one of the reasons it’s so important to polish it often – it protects it and keeps it looking its best. The other reason is that bikes tend to have more intricate metal parts than cars – and they need special attention to make sure they shine.

When polishing the painted surfaces, be careful not to get too close to the edges and curves of the body. It’s also a good idea to work in the shade if possible, as bright sunlight can cause the polish to dry too quickly and leave water spots.

Once the polished areas are smooth and glossy, you can move on to the chrome and other non-painted surfaces. For chrome, it’s important to use a product designed for the type of metal that it is (not all chrome products are created equal). The same goes for other non-painted finishes on the bike – using a product made for plastic or rubber will help you avoid dulling them. If you have leather seats or handlebars, it’s a good idea to use a conditioner or reviver to keep them soft and flexible.

After you’ve buffed the chrome and other non-painted areas, apply a coat of wax to help protect your hard work. Waxing your bike will also give it a deeper, more reflective shine that will look like it just came out of the showroom.

Be careful when applying the wax – it’s a good idea to buff it with small circular motions and moderate pressure. Don’t forget to wipe away any excess wax that finds its way into the crevices or around the emblems – this can dry out and damage them. Once the wax is buffed to a haze, your motorcycle will have a shiny, showroom-quality finish that will last. And it’ll feel and ride better, too! It’s well worth the effort.

Clean the Chain

The chain is the grimiest part of a motorcycle, and it’s essential to start the detailing process by cleaning it. Many professional detailers use a special bike-chain cleaner, but you can use the same products that you would for your car engine (but never spray the chain directly with a pressure washer, as this can loosen the components of the chain).

If you don’t clean your chain, it will quickly wear out and need replacement, and it may even affect your riding experience by creating a rattle or buzzing sound from the loose, misaligned chain. You should also scrub the sprockets to remove any dirt that’s accumulated, and a toothbrush or chain-specific brush works well for this.

Some motorcyclists skip this step, but lubricating the chain is an important part of detailing and helps your motorcycle perform at its best. If the chain isn’t lubricated, it will wear out three to four times faster than one that is properly oiled.

A lubricated chain will also improve the efficiency of your motorcycle, as it won’t have to work so hard to transmit power. This will give your ride a smoother, more consistent feel, and it will also reduce the amount of wear on the rear sprockets.

After you’ve scrubbed your chain and sprockets with a toothbrush or a chain-specific brush, put the motorcycle on its center stand or paddock / chain lube stand. Then move the rear wheel by hand slowly to see if the chain is smooth and free-moving at all times. If it’s tight at some spots, you need to clean and re-lube the chain.

Once your bike is clean and lubed, it’s ready to shine. Whether you’re heading out to the next bike night or looking to sell it, a meticulously detailed bike will get more attention and draw a higher price than an unsightly, grimy one. Remember that it takes time and patience to do a good job, but the rewards are worth it!
