Just finished my bar top… I used Envirotex Lite…. worked pretty good but what I bought locally was just enough for my seal coat.
I set football cards, some postcards and coasters on my oak top and covered it with the clear resin.
I ordered from http://www.MrFiberglass.com – his bar top resin. That was really good stuff and easy to work with. I used that for my first flood coat.
As my bar is outside and will be getting some sun on our lanai, I used Envirotex EX-74, which has built in UV Protection and will help keep it from yellowing. You can find who sells the EX-74 resin on the Envirotex web-site.
Most of the directions say you can use a hair dryer to get the tiny air bubbles out – but the propane torch worked incredibly better than I ever thought.
Another hint – I used plastic packing tape to help stop the spill over on the edges. It can be taken off as the acrylic begins to harden, and if hardened to the acrylic – you can just sand it off.
