Asked around and have 2 recommendations.
#1 Black Cotton Friction Tape
+Made of cotton cloth and a rubber compound.
+Thickness: 3 mils
+Resists humidity and galvanic corrosion
+Rubber-based adhesive helps provide degree of protection from liquids and corrosion
#2 Black Gamma Tape
+Wicks moisture
- most rolls come pre-cut; shorter than the molding
Think the friction tape is probably the better solution.
Let you all know in 20 years if I had a problem! LOL
