How to Spray Primer on Brake Calipers

Video Transcript

"Hi, I'm Doug. I work with twenty great guys in St. Louis at Doug Jenkins Custom Hot Rods and we're going to do some work for you today on Expert Village. Andy's adjusting the gun to get exactly the right pattern, the right amount of material and air mixed in there, so he gets good coverage without too much dry over spray; too much paint waste. You saw when we were unpacking these from the boxes over there when we were pretending it was Christmas, that we took all the bolts and all the hardware out and now you see them hanging from the ceiling by bolts. Andy went and got some junk bolts out of some other calipers so we wouldn't wreck the new ones that we're using that are all nicely cadmium plated. You've got to have something nice to hang the rig from so he got those. Painting a small piece like this, or priming it as we are now, the way to figure the amount of material to mix, is to take the piece that your painting and then quadruple it if you're figuring on painting a flat surface. You can see a lot of material is going in the air. When you paint a complicated piece like this you're spraying at all different angles; you just waste a tremendous amount of material. So Andy has mixed up enough primer so he could paint something about the size of a 4X8 sheet of plywood. That's about how much material it would take to cover these calipers because there are so many little angles."
