Polishing is H!ll
The area of filliform corrosion has been a tough job so far. I got the black emery bar that was suggested on the Airforums, and a new polisher with the sewn cotton thick pads. It is cutting through but still very slowly.
No rush and the pollen here in GA is so heavy its hard to work outside.
But hopefully the 10' shine will be better in a few weeks. This corrosion is a bear to get off!
