Finishing soundboard under/backsides

[James Grebe]

I have for a long time trying to find Epoxie clear gloss in a spray can.  I
used to spray plates with the epoxie gold and then finish with clear gloss
epoxie but have not been able to find for many years now.  What is your
source for clear gloss in a spray can.
