Sure some guy is going to have to chainsaw them out - but it won't be me ...and in the meantime I don't have to worry about them leaking or falling out. :) Boat fittings should be part of the boat, and with 5200 they are!
...and has been mentioned, the new de-bonding agent (developed for sissies) takes the worry out of it. (I still use a crow-bar, sledge hammer, and propane torch to get my fittings off - if I ever have to).
