doesn't the retrobrite only last a few years? I heard the yellowing comes back.
I've read that once you retrobrite them that you then need to then coat them with something to block oxygen from reversing the process with time.
You could lightly rub some Armour All on them and then rub it off.
Does it work on black cock? Michael Jackson style?
Would like to know as well. Also, it doesn't affect lettering, right? Have a white game gear that I'd like to unyellow as well.
its the material the plastic is made from that yellows from reacting to the air..
maybe you could retrobrite it and keep in an airtight container or just paint it I guess
Are you near Chicago? I could help out. I'm not a pro, but here's a game boy I did recently.

Ya it does unfortunately. I retrobrited 2 dog bone controllers I got. They whitened up really well, they've been in a box for about 2 years, no light exposure and they're yellowing again. Guess it's the air exposure that does it.
