Anyone try this?
Rustoleum Industrial Acrylic Hardener

The softness of this paint is still bothering me...



Interesting. Doesn't appear to be the usual alkyd enamel hardener...doesn't appear to use isocyonates as the catalyst. The MSDS says you can use an organic vapor respirator with good ventilation, but recommends a positive pressure respirator. If you're just rolling and not spraying (no atomized particles) a regular organic vapor respirator would be OK I think. I've never used this product, but I've used regular hardener, and it speeds up the curing time dramatically. It takes hours to cure "dry to the touch". Leave it in the sun for a few days and it's hard as a rock. It's really nasty stuff though...read the MSDS. Not something to play with if you don't want to take safety precautions.
