   The Home Depot type of anti-oxidant joint compound is perfect and required
if you want it to remain conductive and disassemble able in several years.
Do yourself a favor use lots and put it on both pieces, don't depend on
putting it on one and spreading it the the other.  It will end the corrosion
between the parts.  (other products not tested)
   I live more than 25 miles from salt or brackish water in W.C. Florida and
aluminum corrosion is a big problem here, within 25 miles it is a huge problem.
