I have seen a product before but forget the name, it restores faded fiberglass boats(painted) any ideas or suggestions?
Penetrol
The two options are a penetrant or an abrasive. The penetrant is quick and looks great with a shiny finish, but does not last long because it does not make a permanent bond. The abrasive is slow, takes a lot of elbow grease and leaves a matt finish unless you really invest a lot of time and buff it ito a shine. Once done, it can last as long as the original finish. If the fiberglass has deteriorated so much that it has tiny cracks in the gel coat then all you can do is grind it off and attenpt to recoat with resin. The recoated resin will not adhere well will not be as smooth and durable as the original finish. The tiny cracks are not a structural problem and do not affect integrity. It is OK (maybe better) to just leave them.
Was it GelGloss you were thinking of? Bill
On restorable fiberglass I've use automotive New Finish.
I still have the Dewalt and Porter Cable buffers and a few hundred dollars worth of wool buffing pads. If the fiberglass is badly oxidized you will need the same.
After the heavy stuff is used we use 3m FinnessIt.
