Aluminum pitting
I am trying to polish the aluminum enigine covers on my motorcycle and they are pitted fairly bad. I have the black/sisal , the brown/spiral and the white/flannel wheels for my polisher. The three wheels will polish the covers to a great shine, but there are still some \'ghost pitts\' still visible in nondirect light. I have added some wet 400 sanding to start with, but this is extremely time consuming. Is there a trick that I am missing? or am I just not being patient enough?
