I just put a coat of hi-temp paint on my exhaust manifold, expecting to have an oven to cure it in today. It says it should be cured within 8 hours, by putting it in a non-household oven for an hour at 650 degrees, but not what happens if I wait too long. The oven didn't work out, and now I have a coat of paint I'd rather not have to sandblast off and redo. Is it really necessary to do it within 8 hours, and what kind of fumes are produced that are so harmful you can't do it in a regular oven? Any knowledge/suggestions would be appreciated.

Dont worrt to much about it, I did not cure my parts like it was recommended and it worked out for me. Just make sure you use the 1800 degree temp paint. I have had very bad rsults with the 1200 degree paint on headers, my turbo exhaust housing and almost everything I have tried using white paint on. The black paint stayed on the parts, but it turned grey and did not stay black.

The stuff I used is rated for 900 degrees--do you know how that's supposed to work?

I've used both Dupli-color 500, and Rustolium 1000 with good results... but this was on blocks and cast exhausts, headers run hotter of course.

I'm doing the same thing right now. I went to a body shop supply place and they said definetely use the 1500 degree stuff. They also said it had to cure but it would cure from the heat of the exhaust and that it could sit for a year and then be cured. I'd be kinda sketchy about putting 900 degree paint on. I wasn't thinking and I put some 300 degree primer on my manifold that I am trying to sand off.

You might want to try this stuff from the makers of por15. I haven't used it but I have used the por15 paint and that stuff works pretty good. The stuff is called por20 heat resistant paint. Withstands heat up to 1400 degrees. You can brush it on or spray it. Check out there web site at http://www.por15.com or you can call them at 1-800-457-6715. These people at the # are located in Sacramento Ca. You may have a distributor that is closer to you. That 900 degree stuff is just not going to work. I've made that mistake myself in the past with exhaust headers.
Good luck,
