I've used double sided foam tape + aluminum foil

food) with a bit of scotch tape over the foil to prevent shorting in
repairing Lisa keyboards. Worked just nicely once they were cut to the
right circular shape. Yes, the key feel was off after that, but livable.

I'm sure the foam response is different (different density if nothing
else), but after reading your experiences, I'd be inclined to work
with aluminum tape. It is literally a roll of aluminum foil,
pre-glued, wax-paper-backed. I've used it quite successfully to make
grounding strips on workbenches (just screw a wire to one end and run
it to a ground bar via largish resistor). It's at least as thick as
household aluminum foil, and the glue is quite tacky - more tacky than
the glues I've seen on double-sided foam tape.
Just a thought for another material that might be easier to work with
than household foil, though what you used is arguably about the
cheapest stuff you could find to do the job. If you've had any
difficulties working with it, consider the aluminum tape.
