I have officially decided that expanding polyurethane “Filla Foam” is the stickiest and fastest-setting substance known to humankind.
Memo to self: getting the cleaning rags, thinners and cleaning bowl ready before the job is much easier than insanely shouting and searching for them like a maddened bull, after the deed is done, as the remaining rapidly expanding filler attaches itself to you and you to everything else you happen to touch.
Everyone’s a genius in retrospect.
On the brighter side, the excess hardened extrusion you cut off the sealed holes makes for great props: I’m thinking commedia dell’arte masks; three-dimensional Rorschach psychology tests; ectoplasm for Ghostbusters 3; and fake snot for middle-aged fathers who have to pull out all the stops to still gross out their dad-joke-jaded wife and daughters.
