If you immerse your nodes in olive oil, it shouldn't be an issue, right?
;-)

Otherwise, graphite is the only one I'd reject a priori, as it's a fine
conducting powder.  Personally I'd use WD, but hell, I'd cook with WD if
I couldn't find any olive oil...

(The main issue in any case is to be sparing and not spray it so it gets
sucked into cooling fans.)
