See full version: How To Prepare Fiberglass For Painting
Congratulations! You’ve found the source for the finest fiberglass auto body parts on the planet! Our entire line of fiberglass comes with a white gelcoat finish that is ready to scuff, sand, prime, and paint. The best trick to achieve a flawless paint job on any fiberglass panel begins with the prep work. By following a few basic steps, your Speedway fiberglass will fit well, be a snap to paint and last a lifetime.
The primer used should be compatible with the top coats that you’re using. If you decide to use today’s modern base or clear coats, urethane primers should be used, which also applies to any single-stage top coats. Remember, you can always follow the recommended procedure from your local auto body supplier. The primer should be wet sanded with 400 grit paper or finer in order to mate with the top coats being used. Be sure to thoroughly dry and wipe down the surface with clean paper towels and do any additional cleaning with a final wash or wax and grease remover.
Time to get sanding! Before you begin, be sure the body panels are well supported, otherwise you run the risk of distorting the panel with pressure from the sanding block. One of the great things about fiberglass is the gelcoat finish, which acts like an initial guide coat. You’ll want to sand the part until the gelcoat is slightly dull in order to give it enough tooth to hold the primer. The gelcoat will show off any low spots in the panels by remaining glossy, while the surface around it will look dull. here

Every square millimeter of the finish to be painted will require sanding and prep work. Fill any low spots in the fiberglass. To raise the profile of low spots in the surface, use a fiberglass glazing putty. Work the putty into the low spot, and then sand it away until the area is flush with the rest of the surface.
Furthermore, do I need to prime gelcoat before painting? As gelcoats age they lose their luster and become chalky and porous. If the gelcoat is in good condition with no major cracking or crazing, the job is relatively straightforward—clean and prepare the surface, apply an epoxy primer, sand the primer, remove the sanding residue and then apply the topcoat.
Furthermore, what is the best primer for fiberglass?
Apply an even coat of primer on the awning with a small, trim-size, foam paint roller. Trim-size paint rollers are less than half the diameter and length of a standard paint roller. Pressing hard with the roller can cause bubbles, so use light a light hand. here
Let the primed awning dry. In humid weather, drying time can exceed 24 hours. [links]
Wipe the awning with a rag dampened with mineral spirits or liquid deglosser, which is a similar product, while wearing chemical-resistant gloves and eye protection. This removes the last traces of sanding particles, and the chemical dulls any spots you missed with the sanding sponge. more
Sand the top of the awning with a medium-grit sanding sponge until the surface is roughened.
Roll an even coat of paint over the primer, and let the painted awning dry.
Once your vinegar or vinegar-and-water solution has been applied, allow it to sit for several minutes, then use a soft sponge or nonabrasive cloth to begin wiping your fiberglass in a circular fashion. Due to fiberglass's delicate nature, try not to apply too much pressure when performing this step. After the fiberglass has been fully cleaned, rinse off your vinegar solution with a water-filled spray bottle or a dampened nonabrasive washcloth. If any stains or dirt deposits remain after this process has been carried out, you will need to proceed with the next step. here
Baking soda can be an invaluable tool when it comes to cleaning fiberglass. If any areas of your fiberglass are still laden with filth, you'll need to sprinkle some baking soda onto the dirty areas. Next, give the baking soda a few minutes to set in, then spray some white wine vinegar onto it. This will subsequently create a fizzy reaction that will lift and loosen any caked-on dirt, enabling it to be effortlessly wiped away. For maximum effectiveness, allow the newly formed baking soda and vinegar solution to sit for at least 15 minutes. Once all the dirt and grime has been successfully lifted and wiped away, rinse your fiberglass with warm water. [links]
Start this step by lightly dampening a nonabrasive washcloth and gently wiping the surface of the fiberglass using broad, circular motions. In addition to getting rid of dust, this should also successfully purge any minor dirt deposits. After removing as much dust and dirt as you can with your dampened cloth, you'll be ready to proceed with the cleaning process. more
If you're unfamiliar with how to clean fiberglass, it may surprise you to learn that it's a fairly easy task. With some white vinegar and a few basic cleaning tools, your fiberglass will be sparkling in no time.
If you don't have access to any additional white wine vinegar, baking soda can also be mixed with warm water to create a thick paste that has a similar effect to the above mentioned solution. However, because of vinegar's highly acidic nature, it is generally more effective at loosening stubborn stains than a baking soda and water paste.
