Inquiry (采购产品): media for aluminum polishing I am looking for the proper media to use in my vibratory tumbler to restore the surface on aluminum intake manifolds and valve covers. I would like to clean the objects with fine glass bead in by glass bead cabinet and then lightly polish to surface to make it look new. I also need advice on whether to do this dry or use some liquid with the process. My tumbler holds about 5 to 7 gallons of material. Thanks.
