Do you follow the heat gun with the 303 or you saying wipe it throughout the season to protect?use a Heat gun and it will turn from white to black as you watch, then wipe occasionally with 303 UV Protection.https://www.amazon.com/303-30313-CSR-Protectant-Plastic-Fiberglass/dp/B00KN0UOEE
You can also wet sand it with 400 grit then 600 grit wet/dry sandpaper then again use the UV Protection
Sounds like an easy solution. I will give it a try. Thanks and I’ll take a Budweiser lolYou can use just the heat gun. But I would wipe it with the 303 throughout the year to keep it from oxidizing and turning white. I use the 303 on my car's black plastic trim and wheel flaps.
Make sure it is an "industrial strength" heat gun like this, Master Appliance HG-301D Master Heat Gun 300-500 Degree-MAHGIf all I gotta do is run a heat gun on it, I don’t mind it being a spring maintenance item.
