so well to polish brass, but other auto products do not. I have used nu finish as an additive with good results. on a whim, while shopping at WM, I bought some chrome cleaner to try to see if it would be a good substitute for nufinish. It was quite a bit less expensive. the chrome polish worked, but the brass came out dull instead of shiny like NF. So does NF polish by chemical or abrasive? Wanna kill these ads? We can help!
