I'm looking to paint the entire underside of my gt with por15, is there any certain holes or anything I shouldn't paint over.

Side note, I know this stuff is redic hard to get off and to wear gloves and all appropriate clothes lol

Clean it super well before doing it. My dad did it on his and he used some super bad chemical I forget what its called. Anywho to do it right, take off the body im finishing a body swap and while it was off I super rattle canned it and then rattle clear so it should br good for another 10 years hopefully.

I like VHF chassis black epoxy paint. If applied over clean metal it will last for years and its inexpensive. I only use POR-15 on badly rusted areas. POR sticks poorly on clean metal.

There is really no rust on my car, I like por15 because it is self leveling and really turns out great and lasts long....I have never used it on anything that wasn't rusted so I never thought about asking that. I want something I can brush on, I'm not a huge fan on cans, I am wanting something to prevent any rust from happening and also to look good.
