The paint/coating on the mylar is somewhat fragile.  I received an
SX64 that the former owner tried to "repair" with silver-colored model
paint.  What a mess.  Fortunately I had a spare KB I got from a
defunct Commodore dealer.

I never did find a way to repair the first keyboard.  If anyone knows
how to fix oxidized silver traces on mylar, I'd love to know how.  I
have a semi-dead Apple Mac keyboard with the same condition.

This process is supposed to reduce oxidized silver back to silver metal...

... and I'm sure it works great for silverware and jewellery, but I
have to be cautious trying it on what is essentially a silver-bearing
paint that's been silkscreened onto a mylar back.

If there's a paint-on product that one can use, I'd like to hear about
that - I also have a damaged RCA terminal - the conductors on the
keyboard flexicable were worn clean.
