Thanks..
Yeah I probably could have used just the Pond Armor with the fiberglass had I done this to begin with.
To cover the bottom in fiberglass & epoxy I used 2x 1.5 gallon ACR kits of epoxy. So around $170 worth of epoxy.
Lesson learned here is use the MAX ACR and fiberglass first, then coat with Pond Armor afterwards.
I am leaning towards eliminating the Pond Armor due to Cost and just use ACR (If there is another tank build someday).
Max ACR is thinner than Pond Armor so it is very easy to work with. Roller, brush, scraper all was easy to work with using these tools.
