Yes, I do. I used silicone as a potting material for a few metal can capacitors...until the stuff ate some new capacitors, ruining them.

A friend of mine who works with marine electronics once told me that the company he works for was experiencing problems with some sort of outdoor control box.

He opened the box to find all of the copper had been eaten away - the box had been filled with silicone in an effort to keep out the elements.

Needless to say, now if I need to pot something, I use hot glue instead.
