I am gonna be polishing my wheels and i have heard that many use zoop seal if you have done this how hard was it and were can i buy from or can i just leave the surface without any seal

I bought zoop seal to put on my engine parts. Everything is polished and billet aluminum. I bought a new polished alternator and before installing it i figured I would test the zoops seal out on it. I followed the directions exact and it didn't work. The alternator oxidized quiker than my old one that wasn't coated. I haven't coated anything else with it since. And once it started to oxidize, it was harder to polish it out than it was when there was no zoop seal on my old alternator.

So when you used zoop seal was it worth it or no
