I live in the south. It's always humid down here. I hate the stuff. I never could get it to cure right. On top of that, it was about as bad as anti seize for gettin into places you never intended for it to get. It's just a total mess to work with so I quit using it and went to oil based industrial Rustoleum. Just as good or better product and applies very neatly with a brush or spray. You caint beat it.
