I just refilled mine last fall and Ritchie said to use ordorless mineral spirits. They also gave me the number for a local repair place. I called and left several messages and he guy didnt call m back for two weeks. When he did call, he told me that trying to refill it without putting the compass in a vacume was pointless and that could only be done at the factory. He tried real hard to sell me a new compass. Thats when I called Ritchie back and got the info on freezing the mineral spirits. I have not one bubble in mine now. I got the stuff at Home Depot in a small can. I also replaced the dome and seal at the same time with parts ordered from Ritchie. My dome had cracked at the base.

As always, this site has come through again. Thank you ALL for the quick, knowledgable responses.

I will get some odorless mineral spirits and try that first. Probably a cheap fix if that's what it is. If not, I'll call them and go from there.

Not the end of the world, but it's enough to bother me. :(

Just wanted to update everyone on this little project.

Ordered a new Compass Dome and O Ring for my compass. (base of dome was cracked causing the leak)

Got some odorless mineral spirits. Used the freezer method and all is well.

Thanks all!!!!!!!
