Fiberglass is a non-corrosive material that can be used as reinforcement or as a repair patch on almost all surfaces including metal, plastic, and wood. Typically, fiberglass is used for rust repair by replacing the rusted metal and sealing the surface.
Fiberglass is a very durable material that will bond to almost any surface, including plastic, metal, wood and Styrofoam. For laying up fiberglass on hard materials such as metal it’s important to thoroughly scuff the surface to get a strong bond.

Fiberglass resins will not stick to woods that have been treated. They only stick to untreated, clean, dry wood. Redwood is not only usually treated, but it also contains a waxy substance prohibiting adhesion.
Apply Primer and Paint: Apply two coats of Zero Rust paint or primer to the prepared, clean surface. Wait for each coat to dry before applying another. Once the primer or Zero Rust dries, sand the entire area again with 600 grit sandpaper, clean with wax and grease remover, and then topcoat with your automotive paint.
To Bondo or Not to Bondo
Minor surface rust can often be sanded and painted, but major rust pitting and holes may require a little more effort and material — specifically, Bondo or some other quality body filler. However, Bondo shouldn’t be used on every kind of rust hole.

RE: Wax paper, parchment paper & Saran Wrap
