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?

Thanks!

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.

This was poured on _after_ soldering, which was done by hand, in
China, natch.

So such a clear coat is safe to clear with an iron?

(You're right, I'm only tacking in a few extra connections, and
cutting a few traces.)
