I have read not to wax over the decals on the RV as it seals them and will cause them to delaminate. Am planning to wax our V-Lite for the 1st time next month and will use Meguairs Flagship, the same as we use on our 36' Flybridge boat. I do the hull every three years and the deck each spring. I have used Meguairs Premium (auto) on our vehicles for several years and very pleased with it.
We get a lot of sun here and the Meguairs products provide good protection and I am very picky. I apply and remove the wax using an inexpensive orbital buffer - no chance of burning the finish, with terry cloth pads (from WalMart).
Hadn't heard of the Opti-Seal product, but will look into it.
