Camouflage Reusable Elastic Putty for Masking 80 gram

If you want the airbrush boundaries to be a bit blurry (which I do, because otherwise why not just use a regular brush?), then the masking border needs to be higher than the surface you are painting. The spray fuzzes down, so it's not hard line like you'd have with tape. This masking putty works the way it's supposed to and is almost infinitely reusable, but it also tends to ooze/settle down to the surface more quickly than I can be ready to spray everything, so I get a harder line than I wanted.
