Used 7 on heavily oxidized Airstream. Sanded off oxidation. Presto changeo, an almost mirror-like finish. Will stick with Nuvite. Important to follow instructional video.
This is an amazing aid to my fisning. Something serious inland fishermen should have. My only regret is that I didn't have this over the last 20 years.
I bought the same hat 2 years ago to wear when I travel in Europe. People don't ask silly questions about the US. The hat fits well and looks great! Clearly marks me as Canadian.
