It needs to peel off easily. The silicone caulk I have used has always
stuck very firmly to metal.
I think if you were dealing with something "fine" you
would have a problem. But, if you can firmly grasp the
one piece and peal back the caulk, it doesn't seem to be
a problem.
I often use this to make molds from "positive" articles
instead of a more solid-setting material (e.g., plaster or wax).
The downside with any of these is that there is a
"drying time". I don't imagine the folks using
this bit of kit would sit around waiting before
reusing (or retiring) it. <frown> Imagine having
to similarly clean a 'scope probe between uses...
Yes, this is very much a specialist tool for getting metal debris out of
magnet gaps in moving coil meter movements or disc cutterheads, where
time is not a major factor.
Different use pattern. The communication cable is used
most like a 'scope probe -- attach to one access point,
examine/interact data stream, detach and move to the next.
I use it for diagnostics, debugging and installing "secrets".
As it is not uncommon for folks (nowadays) to exploit
"internal/secret" access ports (e.g., "to start a shell on
tty0..."), having something other than a 4 pin header to which
you can attach a TTL-level serial device raises the bar a bit.
(having all of the comms over that port encrypted makes it
virtually unattainable!) And, of course, not having to
perforate the case to provide access to same is a win as well!
None of these are activities where the user would have an
abundance of patience...
