My comments, from having made fiberglass front wheel skirts and Kammback:
- Use epoxy resin, rather than polyester. It's much more expensive, but also stronger. (I didn't. Wish I had.)
- if you want a pro finish, 90% of your time will be spent doing cosmetic work (sanding/fairing body filler) to smooth the fiberglass part once it has been made
Lessons learned:
- In addition to using the weaker polyester resin, I didn't make my front skirt thick enough. So it's gone a bit wavy. When it was initially completed, it was smooth & nice. I need to reinforce it with more layers on the back, and possibly re-fair the front side.
I've been buying my supplies at Crappy Tire. It's not cheap! And I'm not sure if I can get the epoxy resin there (may have to go to a marine supply store.)
