Well I did make use of the advice and pulled the backing plate, replaced the gasket and added sealer and then re-torqued the 4 fasteners. Then applied sealant on both sides of the w/p to motor gasket and re-installed.

No leaks now!

FYI. When I pulled the backing plate off, I noticed evidence of coolant in a small machined cavity on the back of the pump housing that should NOT have had coolant. Clearly an indication that the 'dry' backing plate gasket by itself was not sealing properly.
