Freds 73 Scamp restore on a budget
I used bondo over that to smooth it off. And I know plaster would work but I had some old bondo that needed to be used.
This is my mold and will fiberglass over it and console will be pulled off it when it dries and will finish shaping it to fit the car.
My thoughts are to use vinyl or carpet on the sides and and the top will be polished stainless steal with some wood grain to match the interior.
Hope it works. lol
