YMMV but for most people (including me ;-) cleaning and possibly a bit of light
sanding is all it takes and I think it's worth while to try that before
spending money on resurfacing the plungers.
For that, aside from the kits like the one you mention folks have used
rear-window-heater repair kits and also glued-on hole-punched foil disks. I've
used both on other keyboards, especially remote controls, but FWIW none of the
PETs I've worked on needed more than a good cleaning.
Maybe it depends on how and where the PETs have spent their lives; I've got
four on the bench right now; I'll let you know how they turn out ;-)

I re-and-re'd my keyboard and keys 3 times... Scrubbing away... each time it
got a bit better, but never perfect. Then I put my 4016 away for a few months
and when I broke it out again I was back to most keys not working. A year ago
I used circuit works keypad repair kit [CH-CW2605] and all is good as of today.

Usually all it takes is a bit of a rub down of the pcb with a *soft* eraser
and a good cleaning of the pcb and the key contacts with alcohol; in stubborn
cases a *very light* sanding of the key stems with fine grade emery cloth does
the job. Unlike cheap remote controls it's very rarely necessary to coat the
key pads with anything.
I should have an apostrophe key and spring somewhere; I'm not clear whether
you also need an R key or just the spring?
