I got a can of Blue Magic and a can of Rolite metal polish this afternoon. In a totally unscientific test I worked on a couple of areas by hand with each product on the front of my Tradewind. The Blue Magic beat the Rolite hands down on how fast it cut though the oxidation and brought up a good shine. Both were terrible for the corrision, pits, and scratches, no matter how much elbow grease I poured into it. (kind of expected that) Both were about the same for mess and cleanup.
Conclusion - Once I get that shine Blue Magic looks like it might be the way to keep it, cuts though oxidation fast and has a good shine. But like what has already been said by Shari and others some abrasive action is needed especially in areas like the front of the trailer. Still pondering the silicone issue.
I have been wondering about giving the trailer the once over with the Blue Magic for a fast shine. Then going over the rough spots with Nuvite F7 or Rolite prepolish and then going over those spots with Blue Magic again. But then the short cut thing leave me feeling guilty so maybe I'd better leave it as got a thought.
P.S. If anyone would like to conduct more unscientific testing I've got a approximately 21.999 feet of Airstream availible (not including the tongue)
