I'll second ChuckH's opinion. I understand silicone can get into the pores of metal and under ribs, etc. and cause problems with rebluing too. I know several automotive body refinishers whose comments on the problems they have with silicone contamination would not be fit conversation for drunk sailors. Great stuff for waterproofing leather boots though.
