Finishing soundboard under/backsides

[Farrell]

Epoxy is a two-part system. Resin and hardener. Not sure what epoxie is.
Anything that isn't two-part isn't real epoxy - maybe something related
though. Hard to imagine real epoxy in a spray can. Would have a pretty short
shelf life I should think!  ;-)
