Whenever I zainoed my car (got about 12 coats on it so far :D) I sometimes get a bit of the polish onto my plastic trims, and when it dries it kinda makes the trim's black fade. I couldn't figure out what to do about it for the longest time until I saw Mothers Back to Black Exterior Bumper and Trim Care at the local car care shop. Works AWESOME, my trims are back to what they looked like when I first got the car and it removed all the oxidation which caused it to fade. Thumbs up to this product

 

Back to Black only worked a few weeks for me. After that, the wax reappeared. Peanut oil is a cheaper and longer term solution. So is peanut butter, if you can't find peanut oil in your cupboard.

 

I agree with Whovous.

The Back To Black only works for a week or two for me. I second the peanut oil reccomendation. Now that works wonders, and theres no way I would have found out about that solution without NAM.

 

Back to Black is very greasy and washes out fairly quickly. Try Aerospace protectant 303, Vinylex, Peanut Oil or other high quality exterior plastic trim treatment.

 

How exactly do you use the peanut oil? Just put it on a rag and wipe on, wipe off or is there a more involved process?

vin.

 

I agree...back to black doesnt last long...and then it becomes nasty.

I'm still looking for more options

 

I've used it to remove the wax residue left on the black trim after waxing. This is residue, not oxidation. I use a toothbrush with a little peanut oil on it and gently brush the surface.

I also have had spectacular results with Aerospace 303. In fact, my twice yearly routine is to carefully clean the black trim with car wash and a soft-bristled brush, apply two coats of Aerospace 303 then finish it off with Griot's Speed Shine. Then whenever I use Speed Shine on the paint, I do another coat on the trim. The result is a deep black color without being greasy or shiny. Really "pops" on a LY MINI.
