I do like to spray my models to undercoat them, as I find that the paint sticks better to the bare resin, plastic, metal as opposed to using a brush.
I do not like to spray my models, as no matter how I use the spray can, I seem to get in a real mess with paint dripping from the can, over my hands, on the floor, all over the place!
I now put a plastic (sandwich) bag over my hand when using spray cans, as it can be such a messay affair.
Am I alone or do you have problems with spray paint?
Keep tension in the bag when spraying. If the plastic goes slack it will slip down over your finger and get in the way of the nozzle, resulting in the dreaded splatter-pattern!
