Insulating trace side of PCB

[CodeMonk]

Due to space constraints, my current project well be using PCB mounted pots.
But the pots will be mounted on the trace side.

Anyone that's done this have preferences on insulating the traces and leads from the pot bodies?

I was thinking about using a thin sheet of plexiglass with some hot glue on the four corners of the PCB.

Suggestions?
Your favorite ways of doing this if you have done it?

Having the traces still visible is a plus, but not 100% necessary. As is the ability to remove whatever you use for insulation, as well as something that won't fall off.

I hot glued some transparent plexiglass to my cnc controller board (which had a bare/exposed pcb on the lower surface) - it fell off.

The solution to this aformentined problem, was to hot glue it back on.

Maybe rough up the plexiglass a bit and make sure the PCB is clean?
Might help.

I was also just thinking about maybe a few thin strips of double back take.

Well, I'm gonna try the hot glue and plexiglass using scrap and give it some kind of nasty test.

The industry's answer is die-cut fish paper.

Double-side foam tape.  You can typically find it in auto parts store for securing body panels/trim.  Made/marketed by 3M.
