What is the best way to remove cast marks from cast aluminum?
I am polishing an intake manifold and would really appreciate some suggestions on the quickest way to remove the cast marks. I tried a sanding drum with a dremel but it seems a bit aggressive and the drums last 5 minutes. I also tried a 1 inch 120 grit flap wheel, that went well but I went through the flap wheel in 20 minutes. Are there any other ways to do this? Thanks in advance.
