Hey, I just did this a couple nights ago. I started off by polishing the raised parts of the chrome so paint wouldn't stick to it very well. I then used a little paintbrush and a toothpick for the smallest places to put the paint on the recessed parts. I used a small can of gloss black enamel paint, not sure if "gloss" is correct. Before the paint dried, I streched a t shirt real tight over the raised parts so it wouldn't touch the recesses, and polished the paint from the chrome, leaving the paint in the nooks and crannys. It was time consuming and tedious, but it looked perty darn good!
P.S. I was just up around Edmonton and Cold Lake this past weekend for Maple Flag exercise. You Canadians sure like your classic cars! I couldn't believe how many were on the road!
