I have done a lot of steel finishing from grinding to polish. Not so much aluminum. Usually just leave the tig bead as is. I had to grind the welds on an aluminum hand rail for a trailer. There has to be a better way. I have a grinding wheel for aluminum that is very agressive. Then what? For steel I use flap discs, progressively finer. They seemed to clog up with aluminum. Any magic tricks?
