    We've all heard various miracle methods for cleaning faded, yellowed plastics to make them look like new again... but does anybody know how to intentionally fade or yellow plastic?

    This isn't a Transformers custom, but I figure this is as good a place to check as any. I'm trying to take the Doctor Who Sonic Screwdriver you and make the casing look more yellowed, like the actual prop. Pictures are enclosed:

    [​IMG] This is the original toy, as it exists right now.

    [​IMG] And this is the current version of the prop, as far as I know. Rather, this is an image of the upcoming prop replica. This is how I'd like mine to look. I think the taupe casing contrasts nicely with the metal fittings.

    A friend of mine mentioned how she once tinted a set of bones by brewing black tea and giving them a soak, but I doubt that would work on plastic. Any thoughts?

    you don't want to intentionally yellow your plastics, but you CAN dye them in yellow, or paint them with a thin translucent yellow paint.

    No, I DO want to intentionally yellow the plastic on this. I carry it with me everywhere, and I don't want to use paint because that'll wear off. Dye is a good idea, but I wanted it to look intentionally worn and faded, just like the second picture.

    I get that, but that's not my point. My point is that the yellowing process DAMAGES THE PLASTIC.

    Unless it alters the structural integrity to that of a stale graham cracker, I don't really care. I'm not an idiot, you know.

    Seems to me any uv light lamp or other wise is going to take months for it to become yellowed. to dye it would take disassembly and possiable warpage of the plastic. Paint is really your best option. Paint can hold up better than people think just depends on how its applied and what type of paint it is

    Again, this is something I handle and carry everywhere, every day. I've yet to find a suitable paint that would work. I'm open to suggestions.

    Disassembly isn't an issue. It's very easy to take this thing apart, and I even have spare casings to experiment with. A friend of mine suggested immersing it in black tea to see if that tints the plastic. I doubt that'll work, but like i said, I have spares to blow through. I'm willing to try just about anything.

    I agree that it's probably better to dye. UV yellowing continues to happen long after the UV exposure. It's a chemical reaction, afterall. Thus, after you find the shade of yellow you're happy with it might continue to keep yellowing more and more.

    You could also buy a pack of crayola water based markers and a bottle of future, fill a cup with future, remove the core from the yellow marker and mix it in, may want to add some orange for effect. Then paint it on in thin coats, not only will it look good but future is very durable :p

    Not to mention the amount of time it would probably take.

    maybe slap a bit of acetone on the surface as a catalyst and then hit it with the UV light (but not heat for a while, aye? there is a significant fire risk involved here) since effectively you want to be horrible enough to the plastic for it to start to break-down.

    alternatively, sell it to me on ebay as AFA C-9.5 MSIB G1 , and by the magic of internet auctions it will look like a thousand year old twinkie by the time it reaches my zoo*.




    *because 'collection' would imply some level of competence in buying vintage toys.

    This might be a bit off-topic but your screwdriver looks like a lightsaber.

    IT REALLY DOES. :|)

    *Snicker* While I appreciate the S-Class Snarkiness, I think I'll be hanging on to it for now. But I might try your acetone trick. Sounds like has potential.
