probably many out there
I have used many brands of metal polishers on motorcyles, so it doesn't surprise me much that there are lots of products that work to differing degrees out there on Airstreams.
Biggest area is which is best, consistant, easiest, etc. to use. I think most people want known results and if they are not personally familiar with a polish and it's application go with the old standbys for good reason.
If you are familiar with something different , go for it , and I for one enjoy the new ideas this forum presents...thanks for the heads up on this new to me polish......jem
