Is My Paint Too Old?

[Miatatom]

Newby here with my first question.

I bought some model cars and paint a long time ago (~15 years ago) and am finally getting around to them. The paint is Testors in the small bottles and has never been opened. Is it too old to use? If not, should I do anything to it beyond a thorough mixing in order to use it in an airbrush?

BTW, it's enamel paint.

The only way to tell is to test it. Open it up and give it a stir. I imagine it will take a while to mix. If nothing seems to be mixing after several minutes it probably has gone bad.

Basically, as long as it isn't solid, IE: the thinners in it have dried out and the paint has solidified past the point of adding more thinner to it, then it is toast.

Otherwise should be good to go. I know I have some of those little square bottles here somewhere, that are well over 15yrs old and are still good. Stir it up well, may have to add more thinner, but should be good to go.

Thanks! I'll find something non-critical to test them on.
