Thanks for the replies. I was comparing this to the Aerospace Wash Wax All others mentioned and that product appears to be a Wash and Wax in a spray bottle so was hoping the Protect All spray could be applied the same. It has a pretty thick consistency vs. a detail spray so I was concerned that spraying this on a camper without first washing it might invoke scratching. I can't find anything that clearly states the Protect All is a wash and wax like the Aerospace Wash Wax All product promotes.
I did order the Aerospace Mop and mop head with 4 replacement micro fiber mops to make applying this product much easier than using a ladder.
