Finishing soundboard under/backsides

[gordon stelter]

The epoxy in the spray can is two part( I think ) but
has been prevented from solidifying due to the
thinners, which need to evaporate off before the
catalytic action can occur. Yes, this will make it
less hard than mix it yourself stuff. But spray
something with it and you will see that it is still a
lot harder than mere paint.
     I am wary of doing brush-on application of mix it
yourself on soundboard backs because of lack of
control, and possible deadening build up of the stuff.
The spray cans allow you to spray around beams, up
into corners, etc..
     I'm not an expert on epoxying soundboards ( I did
my last with 2 part catalytic varnish used for bowling
alleys ).
     Show me a  better way to finish the back, and
I'll use it. I have just used spray can epoxy there to
help keep the moisture permeation to a minimum, and
somewhat consistent with what is going on on the other
side.
