(Krylon introduced Indoor-Outdoor as a replacement, but I never liked it as much as the old version )Anyway, the can I used was from around 2005. It is ultra flat black, so it's been used in small amounts. After 11+ years, it still sprays beautifully. I always drop the nozzle in lacquer thinner to clean it. I do this for all spray paints. I leave soaking for a few minutes, then use a piece of brass tubing to place over the nozzle's tube, and blow it out.

At one point you could still find the old Interior-Exterior by the case. Lately I've gone to lacquers like Rustoleums, but colors are limited to red, black, and white, and clear. For clear I use Krylon UV-Resistant Acrylic clears. I've found Testors and Model Masters lacquers are compatible, from the testing I've done.
