Is the hardener for Accraglass epoxy the same as the Accragel hardener?

I don’t believe so. I do know they have different stock and part numbers.

Call and ask them and be sure.

No. Acraglas is a 1 in 4 mixture and gel is a 1 to 1 mix. Gel is a nylon based derivitive and glas is an epoxy. Not sure if I have the technical terms correct. Anyway, you can use over the other after the first has hardened but they can't be mixed.
