It's a very thick coating. People embed coins, photos and all sorts of objects in it. I've seen it used mostly in bars and restaurants on the bar or tables. It kind of looks like varnish but it's much thicker. What is it called? It seemed to be a fad in the 1970's but I still see it quite a bit.
I used the stuff you are referring to, but I can't remember the name. Call a local custom paint suppier, they should be able to tell you. Not Home Depot or Sherman Williams.
Good luck.
