arrowhead, it's not ANYTHING like spraypainting, you attach that - clip to the part you are spraying-- the powder at and the gun puts a + charge on the powder so it is attracted to the - steel part. most of the powder ends up on the part. the trickey thing is to get the part in the oven without any of the powder falling off. i find it helps to preheat big parts in the oven before you even spray them--but be advised, handling parts at 400 degrees can be detrimental to your hands...
OH, by the way, you are right. i spray at like -1LB pressure. the powder just floats out of the gun and gets sucked onto the part. if you get too much powder on the part the excess just falls off.
