I am using a cardboard tube for my secondary also,and I found that using
spray type polyurethane works real well because it is so thin that if done
right you can get the poly to soak all the way thru the cardboard.
I am not sure if this helps to improve coil operation but it sure makes it
moisture proof and real strong.
One note,it takes a very long time to dry!!
