Any recommendations on exhaust manifold coatings. They are needing a new coating the previous owner had some type of gray coating and it's starting to show it's age.

I put this on my 68 8 yrs ago & they still look new. There are so many ways to do this it's almost impossible to look at them all. Money is the big difference.

I painted my headers with hi temp from the auto parts store and one brand peeled off in a month. then I tried another VHT I think and it burned off. I sanded then real good this last time and used a flat and then buffed them and I'm hoping they will last but I'd like to know if anyone has had better luck as well other than taking them to get powder coated which I almost did.

Eastwood was one I was looking at  and POR 15 makes one, I don't have headers just stock manifolds so the eastwood product would work.

I used Calyx on my manifolds and it looked great for awhile but eventually faded back to original so dont use it.  If I would of kept my 77 I would of went with the powder coating.  I have seen them at car shows and they look great.

I painted my whole exhaust pipes from the Headers to the Tailpipe with (2) coats of High Heat Silver POR-15 (5) years ago and they still look great with no flaking...

Powder coating should work as it is supposed to stand up very well to high temps.

looked at a couple of cars that had eastwoods coating on them at a local car show last weekend, the guys raved about the stuff, so going to try it. The pass. side looks like it won't come off with the engine in the car so I may have to do them on the engine. They aren't to bad yet anyway.
