wd-40 and lots of little sanding drums for the dremel. get varying grits too. the sanding drums will do a much faster job than a grinding stone type barrel...and dosent get clogged near as bad. just spray the inside with wd-40 ever now and then to clump the alum shavings together and it also helps to keep the drums free from clogs.
