Hi David and all

I got to my C aluminum door panel inserts today. David's experience rose
my 
curiosity. I have not looked at mine for a couple of years.
I knew they had a pattern, but could not envision them. As we do stamping

in my business I knew it had to be a stamping process of one means or
another.
What I found it is an imprint. A form of stamping using a engraved die
that 
is struck in a press just deep enough to leave the shallow pattern. An 
example of imprinting is when we all see a piece of metal that has a
logo, 
part no., etc. depressed into it.
This panel is not a piece that you want to polish for the reasons David 
experienced. Polishing removes metal and the shallow pattern will be
gone.
There is no cost effective cure to reproduce the process. I also took a 
close look at the panel finish. It is not anodized. Chrysler in the early

days used a process called bright dip. We can all relate to that as we 
climb in and out of showers with an aluminum frame. That is bright dip.
Not 
quite chrome, but shinny. Chrysler also used it on at least 57 to 59 300 
grills. Due to weathering and the elements the bright dip is long gone to

leave dull or corroded aluminum. Brite dip is still done today just like 
shower door aluminum.
At best one could use a fine steel wool or 500 to 1000 grit paper to try 
and remove fine scratches. Forget any deep scratches or other damage. If

it cleans up a coat of gloss or semi clear may make them look ok.
David. There may be some salvation for you. Not to many know that 57 NY
had 
the same panel. That gives you a broader base to find some. 58 may of had

them also. The pattern may have changed like they did on radio and ash
tray 
back ground. If you find a pair of 58 then I won't tell.
