my magnum's plastic trim is turning like white. i'm talking about the strip of black plastic shit on the sides of outside of the windshield. armor all only lasts 2 or three days before it turns again, so i know that isn't the right thing to bring it back. someone told me baby oil, but i am doubting this. it's not starting to break down and flake off or anything. so wat should i do? please help meh. sorry if i should have been able to find this info by searching.
