I am just wondering what is the best stuff to use to get my arches back to black because they are faded really badly
Please help

get some grit paper, p240-800, primer, and black bumper aerosol paint. rub down the trim with grit paper to clean them, then paint them, primer could be optional, depends how good you are if you use p240, prime first then paint, if you use p800 just paint withoutt primer.
