Good Value
A product that should be in every ham’s toolbox. Good value, quality product, reasonable price. Insurance and piece of mind for protecting your connections from moisture.

Superior Quality
I have used other seal products in this form to seal connections on coax and every one except this one got hard and was a bear to replace because the adhesion to the inner layers got tough instead of this one which is much easier to remove after a while of exposure to the elements. I reseal my coax connections three times annually and I never have moisture or corrosion problems using this tape. The bottom line is this works and is easy to work with after it's been taking what the sun and wind and wet/freezing conditions dish out on exposed connections, especially when those are at antenna heights.

Works Well
Good tight seal.

Works as advertised
I used this product almost thirty years ago on my first beam, and continue to use it today on my hexbeam. Easy to work with, malleable stands up to Michigan's ever changing weather.

Good stuff
Think plumber's putty, only a little more elastic. Forms well around joints. If applying at temps below about 50 deg F, warm it up first.

Very moldable and covers all the cracks.
I like how this stuff molds to the object (coax plugs, etc.) and forms a tight seal. My only nit is that it didn't peel away from the plastic backing very easily. Had to work at it with my pocket knife quite a bit to get it to peel away. But, I guess that must mean it is nice and sticky.
