Van's Wheel pants - Epoxy or Polyester?

[MS19087]

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.

Mine were epoxy. One thing I would recommend to anyone is reinforce the mating surfaces and surrounding bolt/screw areas with carbon fiber. I fly from a grass strip and I'm sure they will eventually fail. However, 200 hours and lots of TOs and Landings - so far so good.
