here is my down and dirty rendition of shielding a cap.

automotive aluminum sticky back muffler patch repair tape.
a short section of de-soldering wick.


if this does not work well enough, i will move up to something i pulled from some coax cable i laid out next to the cap shown.
that coax braid is aluminum though so i would need to do a tiny crimp to transition in a copper leg.
