Shine, I hate to see you have to go through all that work. Its enough for all the work you have to do but not ever really knowing what caused it probably bothers you almost as bad. My son has a 66 Chevy step side he and I restored about ten years ago that I will be doing the same thing to sometime in the future. I used Matrix base and who knows what clear, didn't know much about painting at the time, its two tone yellow and white. All of the yellow has blisters and pimples everywhere but the white looks like the day we sprayed it. I dread stripping that sucker, that cab has more body lines I think than any other truck made.
