Well, I just tried out the Plasti-Dip spray last night on a French Cuirassier, using a clear plastic trash bag as a spraying surface. This is intended to be my primer, basically, for all figure painting, as it's praised on various sources for providing a good surface for paint to adhere to that maintains its flexibility.
1) I probably need some type of suspension to hold the items above the surface when I'm spraying. The rubber builds up on the bag around them, and they have to be peeled out of it afterwards, which means only one side at a time gets done. And I'm concerned that when I do the second side, lifting it up will pull loose some of the rubber on the finished side.
2) It makes a lovely black coat, which I may actually utilize by leaving some of my horses black and only painting the non-black parts of the horses. I'm debating this.
3) I'm going to need some Osprey books before I'm through. I also need flesh-toned paint.
