I'm writing this post to explain an option to some of you that want some kind of refresh but not a total redo and don't want to leave it as it is. I'm a pro painter with all the right equipment just to put my comments in context. One of my friends that does me favors was fixing up an old Schwinn for around town riding. He had taken the whole bicycle apart for cleaning and brought the frame up to me for a new clear coat. I addressed a few rust issues with a wire wheel on a Dremel and he scuffed the surface with a Scotch Brite pad. This gives a bit of bite for the new paint to adhere to. I also used a mild petroleum cleaner auto body shops use to get rid of any grease or oils or fingerprints. It gets rid of oil but is not so powerful it starts to melt the paint. He left all the old stickers on. I put an additive into the clear coat paint that cuts the gloss. That prevents it from having the "wet look" we desire on new finishes. I thought the results were decent. It retains the old look but looks fresh. I should emphasize that we weren't trying to make it look perfect, just nice. Not new just reconditioned.
