I bought a product from Adams for use on the windows and plastic pillars, called "Brilliant Spray Glaze". It really makes both look really good at shows!
My wife has a
1993 Grand Marquis that we just put a new short block in, and I promised to detail it if she she kept it a few more years. The window pillars are also a black plastic - also very discolored. But, with several coats of the brilliant spray glaze, they are almost new looking!
