Query: Any metal polishing job needs doing this is the only way to go !

Yes a bold statement, if you don't need to heavy grit polishing and are looking for a lasting luster and shine then a little of this goes a long way. Have always bought in the tubes as you use so little but to do my '72's alloy's I got this can and it will last beyond that for many years. This is flat out amazing stuff and I use it for jewelry as well.
