Gary Nelson at GLNELSON.COM makes a wonderful set of masks making painting of the wheel covers on 57/58 300's possible. However, the the painter finds it difficult to prepare the stainless to receive and hold the paint in the many squares. Any suggestions as to what chemical or process can be used to give the paint a "grip" in these squares without damaging the rest of the cap?
