GITD paint for plastic - water or solvent based?

[gaiageek]

I'm thinking about adding some GITD touch-up to some keychain lights. I see that GlowInc.com has water-based and solvent-based paints. Can anyone say which is better for painting on plastics? Does one hold up better than the other? I'm wondering if I should be looking more at something like GITD nail polish.

Thanks

Solvent Base will adhere better because it will literally fuse to the plastic. However, water-based paints easier and looks better as a result.

Either one would do well.
