We all have, or have seen once-white or light-colored videogame systems and computers with some degree of yellowing, ranging from a relatively innocuous burnt cream patina to puke brown. Retrobriting appears to yield mixed results, and also impermanence. For example, I retrobrited a TV Scoreboard unit only two summers ago, which has already turned back almost as yellow as it was before.
I have several systems--including peripherals in several cases--that could stand a thorough de-yellowing, but I'm increasingly of the mind that simply repainting them may be the better way to go in the long run in most cases. As close to the original colors as possible, of course. I am an unapologetic purist, after all.
I've seen info on this subject for various systems but it all seems to be flung across system-specific forums and threads (or even websites!). Is there a centralized thread that compiles the paints, materials, and techniques people have used to restore the cases of their systems?
Some of my intended projects include TRS-80 Model I (minor wrist wear), Tandy 2, Odyssey 200 (and my original Odyssey, for that matter), Apple //e, Atari 800, ADAM, Studio II, and Intellivision II. But it could be useful for others refurbishing different systems as well.
