Parafilm M is one of those products that should be in every hobby room. Besides masking, I use it to seal my airbrush cup while painting. This has two advantages. First, it makes airbrush cleaning easier, as the paint does not dry inside the cup nearly as fast as when it’s open to the outside air. Secondly, it reduces the rate at which thinners and solvents evaporate from your paint; thus, your thinner-to-paint ratio remains constant throughout your airbrushing session. You should prick the Parafilm with the tip of a hobby knife to prevent a vacuum from forming and to reduce paint flow while you work.
