my friend is looking to make a clear tabletop with beer bottle caps inside...he was talking about using epoxy so i said id try and find out as much as i could before he started buying stuff...so has anyone tried to make molds with epoxy?...any troubles with bubbling?...which brands work best?...fast or slow hardener? any other advice would be appreciated
There are epoxies formulated for exactly what you are asking about. Here is one such example (scroll down to Klear Kote Table Top Epoxy) http://uscomposites.com/epoxy.html
Im sure that many other epoxy manufacturers have something similar. good luck
