You need to remember that "fiberglass" is actually glass fiber reinforced plastic!
I would never apply it to "fiberglass" or other plastic. I'm not sure, but I believe a primary ingredient in Rain-X MAY be ether! It sure smells like ether!

The walls in a GM wet bath are fiberglass, as least the 78 Palm Beach were. The dry bath in our GM interior rear twin is plastic.
