[TowerTalk] sealing connectors

[Art]

Good day all,

I went into my local Home Depot store and expected to find liquid 
plastic/plastic in a can, but they didn't carry it.

I'm trying to seal some connectors that are going to be put up outside and 
don't want to use silicone sealer.

This stuff comes in small cans and you dip your tool handles in it to coat 
them with plastic or paint it on the connector to be sealed and let it set up.

Anyway, I'm not quite sure of the name of the product/manufacturer and not 
sure where else to look for it, which probably means I'll have to mail 
order it?!

Any suggestions?

Thanks,

Art
