Fiberglass sheet metal repair.

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. These air bubbles air bombs reduce strength of repair and can also fail leaving a hole in glass and paint or gelcoat. Once the fiberglass is layed up it should immediately be rolled out with a fin or bubble roller to remove any air trapped in between layers or part. Typically fiberglass is used for rust repair by replacing the rusted metal and sealing the surface.

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. I then used the templates to trace out the patch panels on some sheet metal. Scuff the entire area removing any loose or damaged metal down to solid metal. Fiberglass rust repairs are easily available at all local auto body supply store.
