I repaired a dash this weekend and thought I would do a how to on it. This dash has 1 crack right in the center of the pocket. I made a board that is wedged to the original clips on the back to keep everything straight and solid. You need to grind out the raised portion and clean out under the vinyl. You want your repair to sandwich the original vinyl on the edges of the crack. After that, it's basically bodyworking the repair and then texture and dye.
