We've never tried baking it but leaving it out before baking will
definitely help. Funny story: Had a customer hand us a spec to follow for
using 1-2577. The spec stated that "The coating facility should maintain
15-25% RH when using 1-2577" We politely refused.....and recommended Wyle
E. Coyote's facility in AZ.

Another option is 1-2620---basically a pre-thinned (150 cp) version of
1-2577 for easier spraying.
