303 RV wash and Seal

By far the best RV wash out there. Leaves my 40' Fifth wheel shining and it's terrific for the gelcoat and moistens all the vinyl as well. Use it on the truck and my wife's vehicle as well. Been using it for years. Can't go wrong with any 303 product.

This stuff is great for an rv and it really helps with vinyl decals. Seems to last a long time and repels water and dust pretty well
