Q. In the April issue there was a question about black paint having poor adhesion. You wrote about the oil absorption and bulking values of different pigments. I would have been interested in the gloss of his black paint. I have had problems when the gloss was a dead flat because it was difficult to determine the pigment solids. If pigment solids and the flatting agent were too high, the vehicle would not hold it together. Whenever I could, I would request the gloss to be at least three degrees, then we were able to help avoid this problem.
