FWIW I did a test to check for evaporation b/c I've never really known
how often to apply lube. So I took a strip of 1/4" rubber, weighed it,
lubed it and weighed it again. Then I put it away in a coin envelope.
This was a mistake b/c the envelope absorbed a good bit of the lube.

Anyway, here are the results (and remember the first big drop in weight
was mostly the lost lube that soaked into the envelope):

11/19 - unlubed rubber weight = 3.131g. lubed weight 3.167g
11/20 - 3.147g
11/21 - 3.148g
12/5 - 3.142g

I don't know where the lube goes but I suppose it has to be some form of
evaporation. I guess my plan will be like it always was - feel the
rubber and decide if it needs more lube.
