I did my 39 standard dash. The dash was pretty nice to start with, but someone cut two 1 inch by 1 inch holes on each side of the radio area. I pulled out the dash first, not that hard, filled the two holes with fiber glass from both front side and back sides. I masked off the area to as small as I could , test fit the radio head of course, then primed. The original base coat that the factory used will be on the back of the dash in most cases. But I didn't use that color. When touching up the primed areas, the goal was to come close to what the existing dash looked like , being that it was 73 years old.To do do this, I looked at the coloring on the existing dash. On a 39 standard, there are two colors for the most part. I think that 37 was the same. I had two spray cans mixed at a custom paint mix shop, and began to experiment with old sheet metal. I quickly learned that " spray " wasn't going to work. Back to the paint store. She mixed two small bottles of paint. When we started the process, we actually mixed a little of each, along with a little thinner to first do a background. We used artist brushes. My big concern was that anything we put on the dash, would show ridges. We worked in very small areas and once we were happy with the base, we would drag a little of the stripe color thru the part dry base, to soften the effect. The goal was to try to improve what we had, by a percentage, and to " fool the eye " we did NOT want this to come out new looking. Our goal was to make it look 20 years old , instead of 75 years old. I was not really happy when we were finished, you could see a little too much of what we tried to do. I then took the dash to my local body guy, who put 3 coats of clear on it. That did it ! It softened all of the extra touch up we did and seemed to almost take away the flaws from our work. After assembling every thing, I was very happy with the result ! If your dash is pretty good already, and does not need touch up I think 9 out of 10, will be very happy with a couple coats of clear. But go to a professional DO NOT USE SPRAY CANS ! will try to get pics up.
