Any body knows what are the front seat side bezels made of ? Mines were with many scratches, and I ended up using sand paper and take the hard coat out, until I reached what I guess is aluminium, that I polished. Looks new, but not as shiny as the original. I don't think a varnish could bring that shine, and it was quite hard to take it out, but I would be surprised if a chrome coat is that easy to sand off.
They're aluminum... Got any 0000 steel wool? Rub gently with that stuff, and it will help bring out some depth and shine.
