[TowerTalk] Cushcraft R5 sealing of the traps, What sealant

[Bill Winkis]

The world of shrink tubing has come a long way...look at the 
below  address....just skimming the ad I see tubing at 3" offered 
.... I use their HD adhesive type on all my connectors and it is 
something else....I took a piece 2 foot long applied it to RG213, 
weighted it on a set of lab scales......then shoved it into a flower 
vase filled with water.....pulled it after 30 days, dried it. an put 
it on the scales......Zero weight gain.....so..Judge for your self......
