    Before I begin mashing the toy with stuff, does anyone know any decent tricks to aid restoring discoloured plastic. I have the infamous white -> yellow plastic problem, I heard an old wives tale that whitening tooth paste helps?

    Cheers

    I'd never heard that before. I know that alot of times, white plastic is yellowed by UV rays, so I would imagine that some sort of bleaching agent would probably work. I'd be thinking just an even coat of white spray paint would do the trick, but your solution sounds more interesting.

    Let me know if the tooth whitening stuff works well, I got a bunch of old stormtroopers that I would love to see white again.

    If its jsut smoke damage then Whitening toothpaste will work a little since it scrubs off the top layers of the smoke residue. However even then it won't be completely white. If its mostly UV damage and plastic aging then you can't change it and your only option would be paint.

    Anything that effectively whitens the plastic will also likely take off the factory paint.

    The yellowing of polystyrene is not a reversible process. It is a chemical change in the material. Your options are to remove the yellowed plastic to get down to unyellowed base material or to paint it.

    cheers chaps any idea on what paint I should use, I have some games workshop type paints from the long ago. But I think it is likely to wear off and give a rough finish.

    thanks for the help and time everyone

    I would get a spray on paint designed specifically for use on plastics. Tamiya makes these, as well as Krylon (fusion). These paints once cured will give you the best adhesion. It helps too to sand down any potnetial "rub" points before painting.
