I painted a couple of front panels with the same color as used on the S-Line
front panels. They looked great. Yes, they're not authentic, but I wasn't
painting them for the government either.
I would think the biggest problem might be keeping an old panel flat for the
engraving process. I think a list member, Hank, may have done this, though.
I think he passed them through a significant amount of flattening,
smoothing, and conditioning before machining them.
Whatever you do, if you engrave them (or restore previously-engraved
panels), it is ill-advised to attempt to have them powder-coated. BTDT and
the results are very "iffy". One panel turned out good, the other had to
have the engravings filled in, sanded smooth, and silk-screened. Long,
boring, sad story.
Good luck with it.
