Rejuvenate your car's interior!

You can recondition the plastic/vinyl on your doors, dash, seats and console areas, or do it all, including the carpet, velour and upholstery. You can recolor just about everything in the interior. If you vacuum and shampoo your vehicle ahead of time, you can complete the whole rejuvenation process in a single weekend (allowing for drying time between steps).

Get the right materials and prep the vehicle

Several companies make reconditioning products, but we chose SEM because it's the brand most professional shops use. Plus, it's available at many auto parts stores and online sources (such as and SEM makes products to repair and refurbish plastic, vinyl, velour, leather and carpet.

Match your colors

SEM makes refinishing products in more than 50 colors, so get the color chart from a local dealer and match color chips to your carpet and plastic parts. This process isn't designed for changing colors in your car. You'll get the best results by choosing colors that are as close as possible to the original ones.

SEM offers a wide variety of colors, so you'll most
likely find yours.

Vinyl and plastic

It's important to buy the correct “plastic adhesion promoter” with the kit, so take a minute to watch the training video at to determine the type of plastic you have in your car. Adhesion promoter helps the color coating “bite” into the plastic. You'll also need the manufacturer's cleaner and prep materials, scuff pads, a nylon brush, masking materials, nitrile gloves, a respirator, eye protection, and clean, lint-free rags.

Carpet and velour

Prepare the vehicle by vacuuming and cleaning all surfaces with household cleaners. Shampoo the upholstery and carpet and let everything dry completely. Then move the car outside to a shaded area and roll down the windows (the coatings have a pretty strong solvent smell).

Mask off all areas you don't want to recolor, and cover the seats and carpet with a tarp to protect against overspray. And, if you're coloring the carpet, consider removing the seats rather than masking around them—you'll save time and get better results.
