Let's Reinvent the Seat!

Idea 2: Obtain short pieces of glass fiber, mix with 5 or 30 minute<< epoxy at a
ratio of about 30% fiber/70% matrix, put it all in a ziploc<< bag and hold it in
the desired shape until it sets. Rip the plastic off<< after it’s cured. <<

Ive done a similar thing with a rubber compound. It works quite well but
you’ll never get a smooth finish, it always comes out with a kind of folded
look (from the creases in the bag). Its actually quite a cool effect so long
as you expect it.
