                                                          indoor / outdoor carpet is polypropylene, there is no paint, that can be bought at Wal-Mart, that will stick to it. You will have a monumental mess after the first rain, travel, or excurstion on the new paint job. If the carpet is just faded from the sun, try Armor-All
