I hope this message finds you. I have a 72 Grand Prix with OEM Honeycombs that looked good but just need a little TLC. I have seen older post that you are on regarding refinishing them. While mine are not in horrible shape I would like to topcoat them for a fresh look. I see the following product available OER Factory Wheel Coating 16 Oz. Low-gloss Gray/Silver K89315. Are you able to help with some advice on prepping the wheels (cleaning, priming) before I spray.
Thank you!!

Which kind of engineer? I worked at WIII channel 64 in Cincinnati back in 84. I am a television engineer. Thanks for the measurements on the TA. Mine will look better with your help.
