One thing about epoxy is that for the most part what we as builders buy is a proprietary mixture that the supplier is mixing up. There are numerous additives to make the epoxy act the way any specific supplier wants it to act. I'm always on the lookout for good, and better, epoxy at a reasonable price. I have read the same stuff about this epoxy as posted in other messages...ie: that it is at least acceptable. The owner of Progressive Epoxy certainly seems to be open with information and the price is good. I'm going to try it one of these days...and at the same time ask that company all the questions I can...see what is the response. Let us know what you think of it if you use it.
