Here's what duplicolor metal cast (the anodizing paint stuff) does to old faden indicators. This was the orange can, I also have a yellow can that I was going to do some fog lights with years ago but never got to it. Anyways, I just washed them, 1 coat inside and coat the outside till it looks right. Designed to go on shiny surfaces they reckon. Cheaper than nite shades, so I might get a red can to do brake lights
