“I took my 67 to a Lanny Hussey at Custom Cars to have him put in a new felt sunroof seal (aftermarket seals don’t quite fit right, so if anybody knows where I can find an NOS sunroof seal, I’m all ears!). Lanny removed the sunroof and taped the roof edge to keep any glue/scratches away. When he pulled off the tape, the paint was much lighter around the edges. He buffed it out to blend in the color. He suggested I give it a good polish, so, I grabbed my Carnu-B car wax when I got home and a couple of microfiber cloths and went to work.
It was magical to see the original Zenith blau paint reappear after all these years, or as our Jay Salser so poetically put it, “… it is amazing when the color leaps from the past and glows once again.” I started with the roof around the sunroof and then started on one side of the roof. I couldn’t believe my eyes at the contrast. On one side, a glass-like, light blue finish, and one the other, a dull, bluish-grey. The next day, I started again, small sections at a time, being careful not to let the wax dry before rubbing it off, as per the instructions. I could see the blue-grey oxidized original paint coming to life again before my eyes, so I kept at it. Six hours later, I had polished the entire car. I even did the metal dash and the doors. Magnificent! Zenith blau is indeed a beautiful color.”
