I don't know if this will work for what you're doing, but these people make a nozzle for Plasti Dip cans to help increase coverage so you don't have the pinhole problem. https://www.dipyourcar.com/product.php?productid=70&cat=13&page=1
You may be able to use a nozzle from some other spray can you have laying around. That might be worth a shot as well.
Also, if you want a smooth look you can also paint a layer of Krylon fusion paints on to the Plasti Dip, and then wet sand it until it's as smooth as you want it. I think this method combined with the dip nozzle from that site would produce the best results over all. You could get nice base coverage with the Plasti Dip, and then wet sand out any problems you have during the fusion stage. Then you could add whatever paint you wanted onto that with little to no problem.
I am not too sure how well the paint will hold up when the foam flexes, but it might be worth testing out. I know Krylon Fusion paints were designed to flex a bit as long as they were cured properly, but to what extent I am not sure.
