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.
