Hacking a Park-Zone POS to make it work accurately, I find the PCB has
a relatively thick clear coating.

What's the best way to remove the coating without damaging components?

It decomposes at soldering temperatures, allowing local probing and
repair with a soldering iron. It's clear, so you shouldn't have to
remove it entirely, to do what you're trying to do.
