re: What the heck happened?

Thank all of you guys for the ideas and experiences you have had with epoxy coatings. 95% of the bubbles burst upon application of both coats and after about 10 minutes I waved a torch over the surface and got the rest of them. Paul the base coat was crystal clear and the instructions say nothing about sanding before the flood coat. I have since repoured the piece and it seems fine so far. I did buy a new supply of epoxy fearing the possible of shelf life on the first bunch. Thanks again to all.
