good find.I just found this comparison. I don't know if you got your black trim back looking good or not, but I figured this was interesting and relevant, none the less.
pretty much, that would be the only way to make it stay shiny foreverremove, scuff, paint, clear.
would be the best protection
Follow up:good find.
My roof trim is finally starting to show its age, so i'll be using my back to black on it tomorrow and then seeing if i can find that forever black stuff maybe.
MIne were pretty much perfect up until now, (3.5 year old car) and there is only early signs of age so i figured i'd tackle it now to try and keep it nice.you know its funny, i see everyone always complaining about the plastics on the car, but ive never put anything special on them, never use armor all or anything like that, and mine look like brand new...
