To repair vinyl seats in a Ford F-150, use a vinyl repair kit that allows you to prepare the damaged area, apply the repair material, and dry and color the repair to match the seat color. The repair kits come in various sizes, so you can match the size to the repair job. It takes some time, but no special skills, and it costs less than a professional upholstery repair service.
Thoroughly clean the area around the damaged vinyl with a foaming solution and a scrubbing pad to remove any grime or coating treatments that may interfere with the adhesion of the repair material. Mask off the area to be repaired, using tape.
Apply several thin layers of the patching material with a palette knife. Use a heat gun to cure the repair compound. Press the contoured flexible material that matches the grain of the upholstery against the repaired area, to give it the same texture as the rest of the seat. The textures are available in finishes from satin-smooth to pebble grain. Allow the repair to dry completely.
Clean the area again so that the dye sticks, and color the area in light layers until it matches the surrounding upholstery. Working with one of the various tints available, mix the tint to match the aging of the seat.
