I currently have my interior stripped and noticed how yellow the face of the rear window and pillar trims are compared to the backs.

I'm guessing this is down to exposure to sunlight (or smokers in a previous life?)

I've tried bleach and Oxyclean, and even a Magic-Eraser, but nothing is getting them back to the original colour. Anyone have anything else to try, or recommendations for a shade/brand of paint for these bits?
