I've been using 303 on my roof and sides every 6 months. It worked great for the interior on a previous boat, but one side of the RV is starting to look a little oxidized. Any thoughts on using a wash/wax more frequently? I'm thinking about using one every 3 months, instead of the 303 on the sides.
