Not sure what would be a sealant for wax, but I use and am pleased with a product called Voom. It is an easy spray and wipe shine/UV protection product for RVs. It was recommended to me by an RV dealer a number of years ago. He claimed it was the product they use on all of their new and used inventory. I’m actually more interested in UV protection than a nice shine. Also, given how big my machine is I appreciate the ease of use.
