cracked dash pad
I rebuilt my B-body dash pad. They have a similar "vinyl covered foam" design and cracked badly. In simple terms I ground down every crack removing anything loose. Then I filled each crack with Fiberglass Jelly in progressive steps until it was filled. Then I used Polyester body filler (Like Evercoat Easy sand) to allow for a perfect smoothness. After that I applied texture to match across the whole thing by using spray paint and then "dry-rolling" the area with a foam brush of a close texture. I practiced off part a lot. I experimented with many blacks (flat, matte, satin, etc.) and found the Valspar "Matte" matched the original very close. Here are some pics of it complete. (I did the same for the glovebox).
Dash is from a 69 roadrunner.
