I bought a siphon gun and a tub of sand from Tractor Supply to do two license plates. I spread a large sheet of plastic out in the back yard and masked up. I did the two plates which took a long time, but it worked well. I swept up the sand and ran it through a screen to put it back in the tub. I did this on a dry sunny day. Moisture in the sand will cause problems. I would NOT recommend this for wheels or any large parts. I have seen photos of people doing frames this way but I think their equipment is a lot better than the inexpensive stuff I bought.
