I would like to paint my cut/guide caps, which are plain steel, unplated, polished 7/8" nuts. I am reluctant to use spray cans because they are so wasteful and hard to control. I'd like to use my air brush set up, but I'm reluctant to pay $15 per ounce for the paint, as advertised during a search for airbrush paints.
I am aware that one should prep to absolutly clean, and that primer is recommended. I want a thin, tough coat. These items never see anything but fingers, so chipping and scuffing is not a problem.
Any suggestions of materials for priming, painting and thinning would be appreciated. We have the usual big-box stores, hardware stores and one Sherwin Williams store in this little burg.
