Mike, when you sprayed your 8 coats of epoxy to cover 36 grit scratches, was it sprayed fairly lightly or heavy? The reason I'm asking is because I seem to have more or less filled 24 grit scratches with 2 coats being sprayed leaning on the wet side. Did I abuse the product...you bet I did...will the test panel die back or sink...it should, because after sanding there isn't enough product to evenly fill the profile left with the grinding disc. I will say I am impressed with what I've seen so far.

I sprayed two VEEERY wet coats and let it flash for two hrs ,It took the whole day to get the primer on then it took about a week to cure..one good way to know if its cured is to DA sand it ,if the paper clogs with little balls its not ready yet...Like you, I dont recomend doing this I was just pushing it to its limits ,I could never recommend something I didnt have complete faith in...
and I'm not easily impressed, I've used about every epoxy that matters and nothing else does what this does,Its not only impressive, its my new standard to measure all others by.if another product comes along thats better or if the price of it gets outragous ,i'll switch but I really dont see that happening anytime soon...
