Hey...let me throw this at ya'll, as well...You know I recently installed a new Exhaust Manifold and painted in the High-Temp (Orange)...How come it came off? Shouldn't it stay on the manifold? Did I miss a step somewhere?
No. Most standard high temp paints only resist heat to 500 degrees. Unless it specifies "header paint" and you see on the can that it will meet or exceed 1200 degrees, it's comin off. It will probably eventually come off even then. The Eastwood Company sells some nice products to coat your manifold that will last a lifetime.
