Get one of those plastic stack boxes that they sell at homies for storying screws, bolts, etc. Has three sides closed, front open. Stretch your mesh over the top and secure it (I used duct tape) on the three closed sides. Leave it just a little loose. Add a little weight in the bottom of the box. Instant mesh jig. Hold your plug up to the mesh and lift slightly to scretch the mesh over the plug. Spray your paint, then drop the plug straight down, flip and do the other side. Scales in under 10 seconds
