Half of the mirror in the head fell off the wall the other day while sailing (Hunter 31). I was surprised to see it was a glass mirror. I was grateful it didnt shatter! The glue on the wall apparently gave up the ghost and it slipped out of the holders. Anybody have experience with this replacement job? Is plexiglass a better way to go? Seems like a pretty simple job, but talking to someone who has done it always helps to avoid any unseen pitfalls.
