Rand-o-proof

What would be the minimum temperature to apply Rand-o-proof?

You can apply it at any temperature I think but according to the Ceconite manual, the colder it is, the longer it could take to dry. "At 57 degrees drying time may be endless."

Note the first coat is required to be brushed rather than sprayed to make sure it fully wets the weave and the substrate.

I experimented a bit yesterday when the hangar was at about 50F and it didn't seem to take much longer to dry/cure than a 70F day.
