I believe the GooGone uses acetone.
D'oh! ?I meant to say naptha here.
Be *very, very* careful using any kind of solvent on the panel, and test an inconspicuous
area
with a slightly damp cloth before applying it any any significant quantity. ? I suspect
the black
paint on the back of the panel is soluable in more than IPA, too. ? Best to keep the panel
on a
padded flat surface and not pick it up and hold it while working.
