Good news is that I bought a whole whack of RidgidŽ power tools so that I could caulk the patio door. Her majesty didn't even ask why I need a cordless resipricating saw, circular saw, screw driver, flash light or hammer drill to caulk. All I told her, before going out, is that I needed a cordless caulking gun (no the powered cordless kind) knowing that I'd have to replace my old FUBAR drill to have batteries for this caulking gun . Bad news is that she will find a whole whack of other jobs for me to use my new tools on.
