We used that on our turbo spider... Where it was applied to cast iron on the turbo, it worked great! Although, it can wear off with repeated application of oil and whatnot.
We also used in on the fabricated headers- not so good there. I think the smooth surface didn't help with stick.
Make sure you are careful around it until you run the car, as it stays "wet" until heated up.
Yeah, if you paint any items that aren't directly attached to the exhaust, it's best to sandblast first for a grippable surface and bake in an oven @ 350*F for an hour. Just don't get caught using your wife's oven!
