Fiberglass is a strong repair material commonly used for rust repairs.
Rusted automobile body parts are commonly repaired with fiberglass, which is a very durable repair material. Fiberglass repairs consist of layers of reinforced fiberglass material that is saturated with catalyzed resin. Fiberglass will bond to almost any material including metal, plastic and even man types of porous wood. These repairs will last as long as the rest of the body if done correctly. All materials you will need to do a fiberglass repair can be found at your local marine supply stores or auto body supply stores.
Instructions
1. Put on safety glasses and grind away any rust from the surface of the metal. Wipe the repair with a damp rag of acetone and make sure all the damaged and rusty metal is removed.
2. Tear pieces of fiberglass mat to replace the rusted metal that was removed. Use as many layers as it takes and tear each one 1/4 inch bigger than the last.
3. Mix a batch of resin in a small bucket adding two to three percent catalyst. Stir the catalyst into the resin using the stir stick until it's completely mixed in.
4. Wet the surface of the repair area with the resin using a 4-inch felt roller. Apply the smallest layer of mat first in the center of the repair and saturate it with resin using the felt roller. Roll the layer flat and remove all the trapped air from underneath it with an air roller. Apply the next smallest layer and repeat the same process. Continue following the same procedure for each layer until the repaired area is built back up level with the surrounding metal. Let the fiberglass cure and harden for at least an hour.
5. Put a respirator on and sand the repair completely level with the surrounding metal using a palm sander with 220grit sandpaper. After it is sanded with the 220, re-sand it with 600 -grit to get it completely smooth.
