I read somewhere that black shoe polish works. I don't know, nor have I tried it yet. I seen these white spots and streaks. All the cleaning in the world won't remove them. It is like the pigment is gone. Black shoe polish might stain the plastic black and offer a temporary protection. It can't hurt. It won't be permanent. One probably has some black polish in a drawer. It could be worth a very economical try.

FWIW I tried using a black Sharpie and - surprise! - it actually shows as a dark brown when next to the black plastic.

I use this on my motorcycle and it works GREAT! People balk at the price but it takes like 1 drop to cover 2 square feet. I put it on like 2 years ago and it still looks wet. I will admit that I haven't driven it much the last two years but I stand by the C4.

My 2021 F150 uses a fair bit of (some kind of) plastic, especially trimming out the top of the bed sides, the frontal area, and here and there elsewhere. White splotches appear randomly on these pieces and the few products I've tried don't work well. I'd welcome suggestions on how to keep the 'black pieces black'. Things for sharing your experiences.

I get white splotches on the black trim around the antenna and wipers, and below the windshield.

Ford seems to have switched to lower quality plastic because my previous 150s never had this issue.
