Gas boiler chimney at roof is rusting

The metal chimney on the roof is rusting, about 40 years old. It has not rusted through yet. Can I paint it with black BBQ (high temp ) paint or would regular paint be OK. Not sure how hot it can get when in use a lot.

Your most immediate concern is to verify the pipe is not rusted inside the building, releasing carbon monoxide, a potential deadly situation. You need to spend the money to have a chimney that meets the building code of the local jurisdiction. Please act immediately.
