Wrenches,
I will add an opinion to this discussion. There is no cure for an
unreasonable inspector. However, if you are connecting non-aluminum
conductors, try using NO-OX-ID A-SPECIAL electrical grade grease.
https://www.sanchem.com/electrical-contact-lubricant.html This does an
excellent job of excluding corrosive liquids and gases from the contact
surfaces. I will continue to use Buchanan crimps and insulators where I
dope the wires prior to crimping with the above grease. The crimp zone
under the (4) indentors of the C-24 tool swage the wire strands into
excellent contact and the grease keeps the joint sealed. If I expect
the joint to be submersed, then a western-union wire-wrap splice for
mechanical strength followed by soldering and encapsulation in
adhesive-lined heat shrink tubing would be my choice. My two cents.

Wrenchers,
Some point back we transitioned from polaris lugs to buchanan crimps/caps
(doping our wires in noalox) for our jbox splices. I know there have been a
few conversations on here about this. Seems like a much more robust
connection than anything we have used prior. But now we have an inspector
who isn't in support of using them for outdoor/damp locations. To be fair
(although it seems like a far superior connection) Ideal doesn't have
documentation to support outdoor use. I know a lot of folks on here have
had solid/long lasting results though. In any event, we may have to
transition away from buchanan crimps and wondering what you all recommend
as your second (or first) choice? Or if anyone has experience with
supporting this application when dealing with inspectors? Do we go back to
polaris lugs? I know there was a conversation a while back about failures
with those...
Thanks for any thoughts.
