i have tried laying it on wet and heavy, but then you get runs on vertical surfaces.
i have shaken it six ways from sunday, made sure the temperature was 60 or higher with the item, as well as the outside temperature, and still no luck.
i'm almost ready to try a light mist of wd-40 on something as a test to see what that would do.
or just forget the spray cans and try the brush on stuff with a foam brush.
