Fiberglass Repair

[Grimesy]

Got a new to me tent trailer and it has a hole in the fiberglass body that needs to be patched. It is approx. 2 inches square. I know I can muddle through but thought I would get a jump start with the expertise located within this group.

Clean the surrounding around the hole. If you can fix any type of solid base inside hole do that. Use fiberglass resin over fiberglass cloth over the hole. Add a few layers of resin once hardened. Sand smooth. Spread a few thin layers over Bondo over the resin sanding smooth once hardened. Spread a layer of red-lead cream to fill scratch marks and wet sand once dry. Prime and paint to match. . .

If you don't want to go to all that trouble, and don't mind blemishes? You can get some aluminum backed patching tape. Use the commercial grade. The kind they use on big rig trailers. Get it at most truckstops. Takes a jack hammer to remove, and is water tight.

It is a website for airplanes, but it applies to all fiberglass repairs.
