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
It makes a big difference
Family HandymanSeveral 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 vinylpro.com and tcpglobal.com). SEM makes products to repair and refurbish plastic, vinyl, velour, leather and carpet. When applied properly, the flexible colored coating won’t chip, flake or fade.
We asked SEM’s restoration expert, Larry Trexler, to show us how the pros recondition vinyl, plastic, carpet and velour. For instructions on restoring leather, visit semproducts.com.
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 car’s 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.
Project step-by-step (5)
Auto interior repair: Vinyl and plastic
Soap and scrub
Apply SEM Soap to vinyl and plastic surfaces and scrub with a scuff pad. Put extra effort into textured and recessed areas. Wipe the surface with a clean, damp, lint-free cloth and let dry.
Spray and wipe
Spray Vinyl Prep on vinyl areas and wipe off the residue in one direction with a clean, damp, lint-free rag. Then spray Adhesion Promoter on plastic surfaces and let it “flash.” Wipe off with a clean cloth. Let dry.
Spray on several light coats of colorant (Color Coat is shown), allowing 5 to 10 minutes between coats. Let the colorant dry for 24 hours before using. It’s important to buy the correct “plastic adhesion promoter” with the kit, so take a minute to watch the training video at semproducts.com 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.
Auto interior repair: Carpet and velour
Spray, scrub, dry and vacuum
Spray Plastic & Leather Prep on the carpet or velour and scrub lightly with a nylon bristle brush as you continue some auto interior repair. Let dry and vacuum.
Apply, brush, dry, brush and vacuum
Apply colorant to the interior carpet or velour and immediately brush in all directions with a nylon bristle brush to keep the fibers separated. Let dry. Then brush again and vacuum. 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. Check out these 46 awesome car detailing tips.
