Whats up guys, i had an engineering project thats due on saturday. We have a few aluminum pieces that we made our parts out of and i was thinking about trying to polish them up a little to give them a LITTLE better look. Anyway, i dont know much about this stuff, so what can i get from the average hardware store or home depot or something that will work? Which grit? Should i start at like 400, 500,700,900, 1500, etc? Can it be done by hand without my hands falling off? Thanks for any tips
