I have done 6 rods now with crystal coat.

First at 72 degrees and 24 hours cure.

Then 80 degrees and 18 hours

90 degrees and 12 hours

Phil said that 100 degrees give a 6 hour cure time

CTS says that anywhere between 64 and 100 degrees is fine.

The results I have received at all temperatures were superb.

My rod room is 65 degrees and a pot time over 90 minutes.
What I really like is using weight, and can do small amounts. Just add hardener then. Multiply that hardener amount weight by (4/3) = 1.34 and add that much resin.

A faster set time might be nice, but the light viscosity makes a light first coat with rapid penetration is the trade off. It also make using a small metal spatula a fantastic tool and I have moved away from using a brush. I can use spatula even on long butt wraps to add and level the epoxy with ease.

Thanks to everyone for suggestion and help.
