high temp paint for exhaust system parts?

[DevinSixtySeven]

the cats i'm running (and presumably will have with the new kit as well) are uncoated, untreated mild steel at the pipes and flanges. what can i coat them with? the converter itself is covered by a shield, i'm not going to worry about that portion, just the sections that contact or are near the headers and y-pipe as those are coated mild steel.

DevinSixtySeven,

Griots Garage sells several products for that purpose.

I use one years ago on another vehicle, and it seemed to work just fine. It was a grey paste that you brush on, and the heat from the motor melts it on.

It sure looked better than rust!

I've used VHT and Eastwood header paint. Just make sure to prep the surface well (rough it up a little bit and make sure it's grease-free)

One thing I always wondered about with the high temp spray paint that you can get at places like Kragen is the curing process. Every can of this kind of paint says it need to be cured at 300-400* for a certain amount of time (2-4 hrs). Thinking that just running the truck at its normal operating temps would do the trick, I have yet to get the stuff to give me the results I was looking for. It doesn't take long for it to start peeling off, despite my best attempts to properly prep the surface and do the curing thing. Guess I just gotta find a big oven

Anyone else had better luck????

I've found that heating the parts before painting makes a huge difference. I've never had the paint flake off when I've done this. You can use a propane torch but a oxy/acetylene torch will do a better job.
