I just bought a 350 engine that needs some cleaning up. I am going to prep the block for paint and try and buff up the intake.The edlebrock intake is aliminum but it looks like it has corrosion on it and has lost its luster. The intake is rough aliminum.What is the best method to buff up or should I paint it an aliminum paint? Also what is the best prep for the block and can I use a spray bomb to paint?
The finish of an original manifold is smooth.
If you must bead blast do it very very lightly, then clear coat with high temp.
Those intakes were not painted.
Try aluminajelly first - that might be all you need.
