I have a '51 Chevy 3604 and I am cleaning the engine side cover. Do I dare sandblast the interior side of the cover to remove all the carbon built up over the years. :confused: I plan on blasting the exterior surface. I used a wire brush on my drill one the interior side and got most of it. I would imagine blasting it would pit the surface too much. I won't do anything until I get a lot of feedback. Thanks, Wada.
