When I first used Glen-L about 5 years ago, I used their SLOW hardner to increase the pot time. Even with that, it seemed pretty short, however, I was able to work with it (quickly).

The thing I hated was the SNOT affect of the epoxy. I know you get this with moisture, but there entire work area was dry and here in So. Cal, 60s miles inland from the ocean, it is VERY,VERY dry. I recently ground off all the epoxy on the boat and reglassed the entire exterior with MAS and WestSystems. There were no problems with these epoxies.

Take care jim gabriel
