[TowerTalk] Liquid Electrical Tape?

[Grant Saviers]

I second the clear EXTERIOR acrylic spray 2 coats over the final 33 or 
88.  Looks good after 5 years.  Underneath for me is the commercial 
Andrew kit buildup of 33 tape and elastomer.

I've found that water can wick under the silicone Rescue and 3M tapes. 
For SteppIR joints it is awesome - 7 years no degradation of the 3M 
product.  Also for wear resistance, it got a lot of use on my sailboat 
turnbuckles to prevent sail and line chafe and snag.

You don't need any additional coatings for it and it'll last for years. Just be sure to let the tape RELAX after cutting it and before laying it down as the last layer. Any tension will create flagging as the loose end flies around in the wind.
