How to protect newly cleaned cast iron intake manifolds? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**COBALT** · 06-18-2002, 11:33 PM

I just got it back from the machine shop from serious cleaning, and it looks brand new, so obviously I don't want it to turn into a hunk of rust. How should I protect this thing? I really don't want to paint it. I want to keep that "new" look, and preserve it. Isn't there some kind of clear coat stuff you can use?

Any suggestions?

Only idea I have right now is to prime it with self-etching primer, and throw some cast iron color paint on it.

I guess you could oil it..........

I dunno, your idea doesn't sound too bad.

Cast color paint is available.

PJ1 makes a rattle-can clear high-temp coating for motorcycle exhausts. If it will hold up on motorcycle exhausts it should hold up on manifolds.

I've used the cast coat as well, and I like it. The can says it's supposed to withstand temps up to 600 degrees.

I think Cast Coat is what I ended up with from NAPA...
