    One great tool to stash in your toolbox is a polypus. (That's a look-up.)

    As for conformal coatings, you can easily apply them yourself with a spray can. Just mask off any exposed electrical connections prior to application. Polyeurathane conformal coating is easy to replay (and remove if necessary.)

    Ah! Thanks for the clarification/explanation! From my pre-retirement tour at NSSF, NLON, I learned how to use alcohol to save PCBs and wiring from the evil seawater demon! After a soaking, a nice bath in isopropyl chases the bad fluid out, then blow it dry, and let it sit for a while. We saved a lot of high-dollar electronics on the 1:1 scale equipment that way. Anyway, thanks again!

    COB, the "Stuff" has to be reapplied on occasion. It's just a fancy WD-40.

    With our use, CC will probably stick for the life of the unit.

    Nothing here is a silver bullet. Use what works.

    It's be nice if we could talk Kevin into CC all his units, but it's probably too labor intensive to be worthwhile.

    All of this WOULD most likely save electronics from the common and dreaded WTC leak.

    'Stumph' I believe was the spelling.

    In hindsight, using it was a fool's errand: It deferred, did not, over time, prevent water induced galvanic action, and mineral deposits across conducting elements.

    I can dunk a lot of electrical/electronic items in fresh water, and it will work for a while... FOR A WHILE!!!! I can dunk a Stumph gooped PCB in fresh water and it will survive a bit longer over time.

    One more thing: you get a PCB wet, then dry it out (never completely), then coat it with Stumph, you effectively trap water in the many crevasses of the items soldered to the board...

    ... THE WATER CAN'T GET OUT!

    https://youtu.be/B3lsJmwNO40 (:38 - :50) Look on entrapped water like it was this guy.

    We've become too glib about the need of keeping our current carrying gadgets dry!

    No, just a CID+ (from '05) hack. Former IPC Designer Council president. Old friends with Gary Ferrari. Trying to get something established with him down here in Dallas for the Lockheed Martin MFC group. That's me, pushing Cu .001" at a time for the past 30 or so.

    Understanding IPC Conformal Coating Standards

    Spray Cans of Acrylic or the Urethane are readily available. When using it, be sure to mask any electrical connector to maintain good contact. IOW, don't coat your electrical contacts or you'll "brick" your unit lol!
    Are you an IPC Instructor? I've been certified for years in IPC multiple certs. Was a 2M (microminiature repair) tech for years before IPC came along to standardize the multiple workmanship standards I had been certified to (NASA / DoD) previously. 2M specs are 10X more stringent than IPC's and gave me a huge advantage when teaching set-up techniques. Spent loads of time removing / applying conformal coatings to PCBs.

    This tape measure device is like a Swiss Army knife. It has extremely accurate measuring, laser line, memory, and other features I forgot already. The retail will be ~$250 and available in April.

    3D printing had some BIG printers and automated for manufacturing.

    And Formlabs has made a production resin printer. It prints removes print and drops it in a bin, then starts all over again.
