What I would like to know is how long the seals last when you use white spirit ?.
£ 28 may seem a lot to pay for the proper compass fluid but I think that I should be able to do about ten compasses with one bottle of fluid .
At £2.80 a compass I dont think that the white spirit option is worth the the trouble due to the doubts that I have over the seal compatability vs the labor costs of extra seal changes.
