OK some priming rules I\'ve learned... for spray.
Swirl the can shaker ball thing around on the bottom and top of the can, AND shake it. For a minute.
When spraying mini\'s, I would spray from 6-10inches away.
Glide the spray over the miniature, holding down the nozzle before and after you pass the mini (ie. start spraying before you sweep over the mini, and stop spraying after you have passed over it)
Oh, and like, don\'t chip off the primer, and keep practiciing and make it smooth, and and and...
