I used Meguair's 205 ultra finish polish and detail brushes to work it and microfiber towel where I could and did it by hand. I wasn't confident at first because they looked pretty bad and the back up lenses were quite yellowed. I started with removing the lenses from the housings and cleaned them really well inside and out. After that I masked and painted the black-out on the molding, then I polished out the lenses. It took a little time but the lenses came out really nicely, I polished them inside and out, the back up light section even cleared up. I also cleaned and painted the housing, I paint the inside with Testor's chrome paint and the outside with a linen white also Testor. I have found that model paint works well on plastic parts like these. I like to paint the inside with the chrome paint to help with the brightness due to being more reflective. It did help with the brightness of the taillamps, although I ended up replacing the 1157s with a LED panel and new housings when I got into the final assembly phase. The first tail light lit pic is with the incandescent 1157 bulbs and then the other is the LEDs. In fairness to the LED's the 1157 pic is with the brake lights on and the LED's pic is just the riding lights.
