@Thresher,
The Army Painter cans don't specify with regard to drying times, at least not anywhere I could find on the can.
If you go to their website and download the PDF guide to priming and painting, even in the guide it doesn't talk about specific amounts of drying times. The only thing it specifically says, or I should say claims, is that with Army Painter spray primers you can begin painting over them quote: "as soon as they are dry". Just a tad vague, lol.
However, at the end of the guide they DO make a point of saying that Army Painter stuff dries super fast, and they use it as a selling point that it's kind of like a feature that you can paint over it soon after spraying.
From tutorials I've seen on Youtube for channels that promote Army Painter products, like Spikey Bits, he says you paint over the primer as soon as its dry. Or to be more specific, he never says that he waits. He just says he paints over it when its dry.
So maybe they use some formula where it dries and cures faster?
I know that some modelers also say they use GW's sprays the same way, they'll start painting over them within an hour or less of spraying, because they dry so fast.
Hard to know for sure. Some people say that you can never paint over a spray primer that quick, yet many do with seemingly no problem.
