jkoenig24 Posted August 2, 2018 Report Share Posted August 2, 2018 Boeshield 303 Protectant might help. It (or any other topical treatment) would need to be re-applied periodically. Link to comment Share on other sites More sharing options...
RandyA Posted August 2, 2018 Report Share Posted August 2, 2018 Best approach is to clear coat it with a high solids urethane when new. This gives UV protection and seals the plastic from the environmental junk that turns it yellow. If it is already yellow clean it with Awesome cleaner (dollar store) using a melamine sponge (Mr. Clean). You can then paint it white using Krylon Fusion for Plastic. It bonds well and holds up to the elements. Kinda hard to find in the stores these days but good stuff.
