Is there a reason you don't terminate using locking banana plugs?
Have you heard of Blue Jeans cable 
ultrasonically-welded terminations include locking banana plugs

Seriously, I would just check from time to time and not apply any sealers or washers.

+1 for locking banana plugs. Furutech plugs suck, stick with WBT and others.

Also, avoid Rhodium, it is just too hard.

Best,

The reason I prefer to use spades instead of banana plug is that the banana terminals stay in a position ease to be accidentally removed by a “ blind “ foot!

If the AQ spades are brass, switch to copper.

Adding a washer won't have any detrimental effect either.
