Yes the sides are 3/4"... but the top is 1/8". Even with the flexing, I have not had a problem with the uniflex. It sticks just as good as the day I applied it.
I used about 2 gallons of Uniflex 255. I also used 2 16oz kits of the CPES.
Yes I sealed up all the edges really good with CPES. I did not do any sanding, other than sanding off my goof from using the wrong roller.
I only used 1 small kit of the epoxy filler. I don't have the sizes handy, but I'll edit this message later when I get home.
The quality is remembered long after the price is forgotten, so build your teardrop with the best materials...
