[i am channeling phantomcow, i am channeling phantomcow...]
ok, i'm putting myself out there for some ridicule but
does anyone have an idea about the permeability of an epoxy resin to air?
my current tinkering pet project is:
coat the surface and edges of the rim tape on my mtb wheels with a thin coat of epoxy to make the rim air tight, install a ust-ish presta valve with removable core, go tubeless on the cheap (and possibly lighter than stans???).
anyone want to tell me why this won't work?
