Fortunately, there are premolded dash covers made to fit most vehicles. Likewise, replacing the plastic panels on the door interior, including armrests and other attachments, is a fairly easy repair. These come with a vinyl filler-paste in a variety of colors. If necessary, the colors may be mixed to get a shade that matches your vinyl closely. If you have more sizable damage, the best solution is a dash cover.
Some people opt for a carpeted dash cover in a color to match the floor carpeting of the vehicle.
For our demonstration we opted for the molded-plastic type to approximate the look of a factory dash. We also took the opportunity to replace the interior door panels at the same time. It's advisable to purchase door panels from the same manufacturer as the dash cover to ensure a perfect color match and uniform appearance. Once you've cut away any raised portions, sand the area so that it is completely smooth. Finally, clean the surface of the dash with an ammonia-based window cleaner to remove any dust or chemical residues from old vinyl dressings, preservatives, etc.
