Thanks, Jerry. None of the electrical supply companies in the city could help me unless I ordered a bulk shipment of a conductive thread sealant used by industrial electricians… So, I went to a little corner hardware store run by a family and they had Permatex Copper anti-seize lubricant that is very thick and brushed on. Made from copper particles so should work just fine. The store sells solar power stuff.
Thanks for your advice.
