I've tried to, but didn't want to invest time in perfecting it. the method I used. I laid down fiberglass resin as a glue and laid fiberglass over it. used a roller to smooth it out. Then you poor small coats of epoxy resin from westsystems(its the clearest. You apply small coats to prevent air bubbles (but you can't get rid of the entirely if done amaturely)The you may have a problem w/ it being smooth, I sanded it down worked up in the grains and then clear coated it. Expoxy is very tricky to work w/. I recommend a lot of practice.
