ok so im doing a custom exhaust on my car. i decided to prime the pipe to make it look better. but i noticed on the directions it said to cure it once its painted and then it had a spot that said "off the car: bake at 200 degrees 400 degrees and 600 degrees for different amounts of time. my question is what exactly does baking mean? ive never used primer for exhausts and dont want to do it wrong and it end up catching on fire. so what does it mean to bake it? and what do i have to do to cure it? or is curing not all that improtant?
