Finally got around to painting with the gloss.
1 gallon gave me 2 coats almost.
So far I like it. Had a couple drips that were not super easily removed,

the next day with a razor blade. After 24 hrs, paint had adhered well, covered well and was durable. Gives a nice gloss finish for a more pro look and should be much easier to keep clean and wash off road grime. So far, I'd recommend it and the price isn't ridiculous either. Must be up to my 13 or 14 coat on the pmf. Can't see any weave at all now.
It's now an acrylic composite membrane.
Having said that, was backing up hill on muddy terrain and gouged a hole from a cypress tree branch about the size of a golf ball. The acrylic composite membrane flexes but the cotton base is very brittle, stiff and rigid, cracked easily on my EPS.
XPS have more flex and strength of course.
But for all who are wondering, it has surface flex but brittle at the primary cotton layer and I used TB3 on only one side. Past experiment making a pmf cot with cloth and TB2 resulted in stiff and easily ripped glued canvas. Added some strength but was easily torn by hand in one direction. 1x2 weave HF, FYI.
No complaints considering cost and ease of fabrication. But it's not fiberglass.
On the road to Shambala...
