Painting exhaust tips

Hey guys, wondering if any of you can help, I've painted these exhaust tips 3 times and it keeps peeling off. I used high heat rustoleum spray paint(the one they use for BBQ) and it just won't stay on. I've done it with the bake on method and still nothing, my last resolution is to get a high heat primer first and then paint but I don't know, whattya think? Any other suggestions...

Re: Painting exhaust tips

When you paint an exhaust you need to ensure you do 2 things very well. First is scuff the surface to remove the "shine" so the paint has something to stick to (I've had great luck with grey scotch brite pads). Second, CLEAN it very well...wipe everything down with soap and water, let it dry, then go back with rubbing alcohol to give it a final clean.

I would scrap those paints..no need for primer. I used Krylon BBQ paint on my RAM when I did the entire exhaust and it was bulletproof, lasted for a LONG time without any discoloring, chipping, peeling, etc...

Here is how it turned out...

Re: Painting exhaust tips

Ditto above. I have the Jeep Eco Diesel and I sanded it down big time. Cleaned it and sanded it and cleaned it again. I used rustoleum high heat exhaust paint and it's been on for over a year now. Don't even bother taking the exhaust off. I just taped up the bumper. I put 4 coats on, and used a heat gun to bake it in each time. Let it sit over night and it was good to go.

Re: Painting exhaust tips

That's the stuff I tried at first but wasn't happy with the matte look, plus the Krylon paint doesn't require a "baking" step although it stinks to high hell for a few days as it cures.

Re: Painting exhaust tips

A self etching primer may help, especially over chrome. It will "eat" into the surface.

Great tip, I'm guessing that fixed the issue. I was thinking it might be a curing issue.
