Removing Yellow Tarnish?

[Martin_Lee]

i doubt strong chemicals is a good idea, but if you want them white again youll have to get that top layer of
plastic off somehow, either sanding or strong chemicals.

i guess you could sand, prime and paint them instead?

theres no other way of doing it.

model paint? noooo! use a matt spray paint or car paint methinks
