I'm always curious ... can you retrobright keyboards? What happens to the letter transfers? Do they block the retrobright process? Do they remain in place?
I will let you know :-) But going by many threads I've read it shouldn't be an issue with keys/logo's.
The Cream peroxide product I'm going to try has good results and you can brush it on. However you need a lot of sun or bight UV light.
Heres a good read :-)
