nineback 0 Posted January 5, 2014 I have a fiberglass sided 5th wheel with lots of decals. I have read many warnings about using wax on decals and particularly waxes that contain some petroleum base. Has anyone used OCW on their RV or use another Optimum product? Obviously given the size of a 5th wheel I am looking at the easiest solution. :-) Thanks, Tom Share this post Link to post Share on other sites
Guest Posted January 8, 2014 If you plan on keeping you unit a long time, investing in Opti-Coat would be well worth it. Opti-Coat will extend the life of your decals and fibreglass. If not ONR washing and OCW are great products to use on RV's. Share this post Link to post Share on other sites
