Gold High Heat Max Special Purpose Aerosol 12 oz. Aluminum by Gold

Q: Will this work on wood? I have a wooden fire pit lid for my in ground fire pit, I want to spray this on my wooden lid.

It'll work on wood but it won't give wood MORE fire resistance than it has already (which isn't much). Wood combusts at about 300° F so this paint is way overkill, the wood will long be burned away while the paint stays. Get the regular "High Heat" paint (this one is "High Heat Max"). This is designed for metal that get's hot so the paint itself won't burn off. The real question is why do you have a flammable lid for a FIRE pit?
