I just bought a 1989 Peterbilt truck. It has an aluminum grill shell that was once polished. The truck is from florida, so its seen alot of sun and I am sure some salt air. I dont think the grill has ever been kept up.
I used some mothers alum polish on it to start with. It worked somewhat, but not as good as i hoped. Took a long time to get just the one smaall spot done. Any ideas on anything better? I have some of your products on a corvette I had – they worked great!
Oh yeah – taking the grill off is not an option. It all has to be done on the truck.
