Took me forever to figure out what these were called and I'm still not 100% on whether or not it's the correct name. But this part https://i.ebayimg.com/images/g/4MMAAOSwTO9aDIHP/s-l1600.png is very dull compared to when first getting the car. It's some kind of plastic but I don't know what product to try and use to restore it's shine. It has seemed to haze up and look real bad over the years. Any ideas on a product that would help restore them?
