Paul That's Stainless Manifold Paint from Chevy Duty. I was really impressed with how this stuff went on it didn't look very good when we first put it on the freshly sandblasted intake but after it dried for about 20 minutes it filled in nicely. In fact I only slightly sandblasted the exhaust manifold (not the good cleanup I gave the intake) because I'm planning on putting duals on as soon as I get the cash to do new exhaust all the way back. So far it's holding up fine (about 200 miles) I had some gas leak down on the intake from the Carb and it stained it a little but I haven't tried cleaning it off yet as the carb needs work to stop the leak. But for $15 I'd say it's hard to beat plus I've got tons left in the can.

Stingray Thanks, I'll have to do some looking around and see if I can locate one in better shape as my wife loves it and the first thing everyone says when I pop the hood is "look at that Air Cleaner". I've been kicking around the idea of working out a way to modify it to hold a newer paper style element. I would just fill it up with oil but it's got several pinholes in the bottom and would hate for it to leak.
