[R-390] aluminum knob/panel paint stripper?

[Cecil]

I haven't yet found a stripper that works on an original panel....the stuff is like stone.  I have tried several with no luck.  I've gone to glass bead blasting the panels and then lightly zinc chromating them prior to top coating.  I usually wait a few weeks for the chromate to fully cure before top coating.  I've had no problems with damage to the engravings.  

Media blasting probably would be better...soda or plastic might be the ticket.

In any event..to answer your question...any stripper will not prep the aluminum panel for paint.
