I hope I am posting this in the right spot.... >.>

For Lina's Inverses (from The Slayers) OAV braclets, I bought a couple $1 watches from Big Lots that are the perfect shape, etc for what hers look like.

I took the plastic off where it tells time, and cut up a small red chirstmas ornament to fit in the middle. It looks freaking great, but the watches need to be grey, not black.

So I bought some of that paint you use on plastic models. It worked on my plastic sword blade, a couple plastic braclets, as well as on plastic easter eggs and tin easter eggs I used for something else.

The watch head drys, on the straps it will not. I let them sit on the straps for two weeks and nothing had changed. I even put them outside in 90* weather for over 48 hours and nothing.

Next Im going to try and wash the paint all of... again... with paint thinger and try sandpapering the wrist parts, and then paint it and see if the paint will bond then. My sisters guess is there's some type of finish on the wrist bands thats not allowing the paint to dry.

Does anyone else have some suggestions? :waaaah:

What about covering the straps in gesso after sanding them down, then putting acrylic paint over that? That should work...

If the paint is running, that's because there's not enough adhesion. I have no idea why it's not drying, but I'm thinking it's because there's nothing for the paint to 'grab' onto, if that makes sense. You can pick up a bottle of a sealer/finisher called "Mod Podge" from any decent arts and crafts store for relatively cheap. Paint on a few coats on the straps and let it dry. Then, try painting the straps once more.

ive heard of painters using hair spray to force paint to dry almost instantly... its like a catalyst or something... now sure if it would work, but you could always try...

Sometimes all you can do is clean up and start again. Any scuffing or sanding is always a good idea for painting or glue. If there is a coating of some sort, a thinner or acetone might cut it. Acrylic is great too- it's a plastic sealer in the end. Luck.

My friend had the same issue with a pair of rubber boots he painted. In the end I think we determined it was the rubber release keeping the paint from drying completely...

Maybe try a clear coat/base coat first then the color again after a thorough washing.

Take paint off, add colbalt dryer to paint (use with caution!!!!!) or another drying agent Reapply.

Those little testers oil paints really don't like to dry on metal or sometimes certain hobby plastics. Next time stick with Tamaya color or even the flat craft paints used on wood. They are water based and dry easily. The outdoors glossy will pool better to get it a flat finish, otherwise you'll have to use a glaze.

Would the watch strap be a vinyl at all? If you are use an enamel spray paint it will not set on it. See if you can locate some acrylic based paint and then give the straps a quick sand with some very fine sandpaper and then give a light spray to test, sand again and paint properly.

Some watches have a sealer on the band to protect it... you might have to go out and find a replacement leather watch band for it. Leather bands tend to accept dyes and paint more readily. If there is a sealer on it, a very fine sandpaper will rough it up enough for the paint to adhere.

There's always 1 more option you may have overlooked... find fabric that is the color you want the watch to be and just use that. It should work just fine for the convention... Though I don't see that approach being a very long term fix though... just a band aid until you get a different band.

option 3: look for 'latex' spray paint, it should adhere to just about anything, and its flexible... when in doubt though very find sand paper to the surface 1st...
