I am kind of mad at myself. When I had my engine out a couple of months back I got cheap. I received a quote of $300 to have my manifolds jet coated. I thought that was nuts. I did some reasearch and found a ceramic manifold coating from POR15 that was rated for 2000 degrees. I had always been happy with their product so I thought heck I'll give it a shot. I bead blasted my manifolds and then washed them in trisodium phosphate (A technique that is used during the powder coating process for bare metal to insure proper adhesion) to insure there was no oily residue left behind and then rinsed very well. Well I was underneath the car performing the first oil change this past weekend and there isn't a stitch of that coating left anywhere on the manifolds. The manifolds are still nice and clean but now have surface rust on them. I used three coats on the manifolds and allowed 24 hours between coats. What a joke! I wish had I hadn't gotten cheap and just had them jet coated.
n a good note I can say that there engine block paint rocks the house.
