Depends on when you bought them
(I am beginning work on the last bit of fiberglass work on my project - installing wheel pants on my mains. My question is simple . . . are they made with epoxy or polyester)
The early pressure recovery wheel pants were made with polyester resin, but the more recent are all made with epoxy.
I think the polyester all have gelcoat as the outer surface. Epoxy are translucent.
