How to repair sheet metal with fiberglass.

Thoroughly clean the area until the rag no. Add catalyst or hardener and mix the resin as instructed. This seals the fiberglass much like a gel coat for a factory perfect finish. The resin should cover the area that extends 2 to 3 inches beyond repair.

Wipe the ground area of the metal clean with a rag and acetone. Scuff the entire area removing any loose. Use the paintbrush to apply a coat of mixed resin on the damaged area. Sanding the repair smooth and then using a body filler and high build primer to finish it.

I used a piece of pvc pipe a vice mount miniature metal break and body hammer kit. You should target a 50 50 fiber to resin ratio for your repair so once you have weighed your reinforcements measure out the same weight of resin. I then used the templates to trace out the patch panels on some sheet metal. Then place a piece of fiberglass cloth onto the damaged spot and saturate it with the mixed resin.

After slicing the patches out with a cutoff wheel next came the bending hammer and dolly session until the patches matched the holes and fit snug and flush into the flanged seat. Measure mix and apply your resin once your patch materials are prepared pre weigh the reinforcement schedule. Keep applying layers of cloth pieces and resin until the area is repaired completely.
