Figured I had better look up the part number that I wasn't sure of for the
Dow Corning RTV.  RTV is a silicone rubber and the right part number for a
non-corrosive (no acetic acid) version is 3140 (not 9130).

Quoting from the tube:  "Dow Corning (R) 3140 RTV Coating is designed
specifically for electronic applications.  It is used to provide protective
coatings for electronic components, especially where compatibility with
copper is essential."

This stuff is a lot thinner than the usual Silicone Rubber and cures by
exposure to moisture in the air--meaning it is pretty slow to cure in dry
climates like Colorado.

Any good CONTEST station should always have some handy.
