Re: Drill out broken exhaust manifold stud- water/antifreeze!

In wanting to clean up my exhaust and intake manifolds while I had my engine apart and not wanting to go the full-monty with porcelain coatings, etc., I sprayed the intake manifold with a high-heat engine paint and for the exhaust, I bought a large spray can of ceramic coating at the local NAPA store. You are supposed to put several coats on and then either bake it in the oven at 475 for a couple of hours, or go through a heating and cooling sequence with the engine. I chose the latter and it would seem the product, whatever it is, is adhering quite well. Obviously time will tell. I thought for a driver, if it cleaned it up and looked halfway presentable, I could live with it!... I only submit this as an economical alternative to the 'real deal' as, sometimes with drivers and less expensive cars, lower cost solutions are sometimes worthy of consideration.... it certainly 'cleans it up'!
