Boat maintenance is a continual balancing act between perfect and affordable and good enough. I’m sure you have lots of examples of maintenance choices you made that had unexpected results. I’m not interested in expected results. We have all done something bone headed in either putting something off or did a bad job with the wrong materials and suffered the expected results. I’m looking for unexpected results either good or bad.
Did you use an automotive product against all advice and get away with it?
Did you just ignore something and it still worked long after the sages said it would break?
What maintenance sins have you committed with no consequences?
What maintenance did you do perfectly according to the book that didn’t work out right?
