Tried the ATL epoxy (test panel) and it sands great after post cure @ 40C for 12hrs. Going to give Daren’s (Entity) idea a go on a test panel and compare.
Just tooling around getting familiar with epoxy. Only used Fiberglass Hawaii Epoxy before with I0 min hardener and found it to be a good lam/fill resin but too stressful in my climate being that I’m not that good a laminator! This ATL epoxy gives a 25-30 min pot life so it’s looking good. Totally agree with comments regarding poly over epoxy I just would’nt feel confident with it.
