Hi All!
Is there any advantage to submerging a cap in an airtight container of oil, 
or would it work the same if it was just in a bucket covered with oil. I can 
stick it in a pvc pipe container with the oil in it (thanks for the leads) 
but my cap is about six inches in diameter and the end caps are about ten 
bucks a piece and if I can get around spending the money, I will. 
Thanks,
Dennis
