They would have to turn out really good for me to go there.
I haven't really done this kind of thing before (that I can remember) so there might be some trial and error in the R&D phase.
I have done fiberglass work before, but that was over 30 years ago.
Maybe I'll remember some of the tricks.
I know for sure I'd pay $40 or even $50 for a pair that I could just bolt onto my car - I know this because I spent more than that in materials.
I doubt there is a huge market for these, but making a pair of them once in a while would keep me in beer money (or shiny bits for my cars...)
