[R-390] Front Panel Paint Removal

[Walter Wilson]

Jerry,

Bead blasting with plastic media works fine, and does not round the edges of
the engraved lettering.  I've never tried anything harder than plastic
beads, for fear of damage to the panel.  The tough panels are still a  bit
challenging even with bead blasting, but it works far better than anything
else I've tried.
