I wash using Meguiar's Shampoo Plus. Microfiber towel dry. I then use 303 protectant on all exterior rubber/vinyl. This is what I use http://www.factoryauthorizedoutlet.c...cts/7336SP.aspto apply eitherMeguiar's RV & Boatpolish or NXT polish and then use microfiber clothes to remove and buff. The RV & Boat polish is specifically designed for fiberglass/gelcoat and seems to last a little longer than the NXT. Both are pretty easy to remove by hand.
