I'd put a couple of drops in a saucer, then a couple of drops of lacquer thinner. Stir it around and see if it mixes OK. If it does, let it dry and see if it cures OK. If it does, try spraying a bit on some junk plastic. If that's OK, then you should be set to go. Be sure it's compatible with whatever your spraying over. Hopefully, you have a well ventilated spray booth or an organic vapors mask.
