To the best of my knowledge, my engine was never rebuilt. The only areas that have more than one coat of paint are those upper surfaces that I sprayed with rattle can "Pontiac Metallic Blue", and a few areas with a dissimilar blue which was sprayed over the black of the power steering reservoir and the natural power steering bracket.
It is highly unlikely that even if the engine was rebuilt, that the rebuilder would have taken the time to strip all the paint from the timing cover, valley pan, water pump, balancer, exhaust heat riser, brackets and repaint them. There is no overspray on the distributor, none on the exhaust manifolds.
My opinion differs from yours.
