Paint is obviously a good solution. You can also treat with 303. Will make them look good but not for long. A friend uses a product, available at Walmart, comes in moist sheets or pads that one wipes on. The name might be โwipe newโ, but Iโm not sure thatโs correct. Friend says it lasts quite awhile and he uses it on plastic bumpers and trim.
