check with your local auto detailers. A friend of mine use to go around to the dealerships and do dash crack repairs. He had some kind of clear vynal filler. He used a pin point heat gun to melt and fuse the filler to the dash, then when the filler was still warm he would match it in by pressing the repair with a closely matching piece of
vynal. After it would cool he would mask and spray a matching finish color on the whole dash. He did a guys car I know and it looked nice. Good luck
