Faded fender flare swirl pattern

Had some odd fade marks on my fender flares. A very symmetrical pattern of swirls...Best I can figure it's a remnant of the manufacturing process. Not your usual faded flares, but, the side that gets more sun is worse.
Anyway, I was detailing paint and decided, fuck it and hit it with Meguiar's Ultimate polish on on orbital before I threw the pad out. After pic is with a coat of HydroSlick.

 

Heat guns work, had a jeep and would have to hit the fenders with a heat gun every year or two. Aerospace 303 will help keep them black for a little while. There are also the cerakote kits, but i have never used them.

 

Took mine and had them coated with Line‐X. Problem PERMANENTLY solved!

 

Another option is ceramic coating like Cquartz D-Lux or GTechniq C4. I can easily get a year out of coating before needing to reapply. Keep in mind my truck lives outside 24/7.

 

What you're seeing is a remnant of the injection molding process. Very common and shows up worse on some plastics than others. Throw in some of Mother Nature's UV rays and, well, you see what you get.

The only true / permanent fix is either dye or paint. (Paint being the better fix.) Everything else is going to revert back to what you have in fairly short order.
