I read an article on this once but cant find it now....

First of all, try to read up on review and find out what acutally works. Don't just buy paint that is marketed as working on hi temp parts. Get the highest temperature rating possible (I found this, and this clear coat. If you really want to go whole hog, you can get primer. Probably not necessary though.


Anyway prepping properly IS SUPER IMPORTANT! Make sure you sand off any rust, and clean with a good degreaser (I like dawn dishsoap, but hey to each their own). If you really want to go all out, sand the entire thing. This is just good paint prep in general though.

When painting, apply multiple coats as thinly as possible (don't let it gob up.) I would do like 4 coats of base, plus 2-3 of clear coat. Make sure and wait a good amount of time for it to dry between coats.

After you are done painting and have the exhaust installed back on (at least a full day after painting), warm it up slowly. So start and run the bike for like a minute, then shut it off for 5. Do this several times, then start increasing the run time. This allow the paint to temper without as much initial stress. After that just ride it, it will bake fully over the next week or so.

If you don't really care about looks or longevity, just get BBQ/grill paint, mask off the areas around the exhaust, and spray that sucker without even taking it off. Should last you at least a year.

I haven't done this yet, but I plan to in the next few months.
