I did'nt think it would be mineral spirits!
I thought it would be mineral OIL. spirits are basically paint thinner, i would have serious doubts that that would work. they would definitely get the same use and abuse since one would be mounted on port and the other on starboard. my boat has a tiller and its next to impossible to read if I'm sitting on the starboard side steering, since my compass is mounted on the port side. I had also heard that some where filled with glycerin. I do know that some very,very old compasses were filled with the alcohol/water mix but that hasn't been done for a lot of years.
