[SCCC] Copper Paste

[Daniel Severance]

Noalox (or any of the other variants) is what I've been told to use as well - without it over time the pieces will weld together so you can't even disassemble to clean up joints.  I have had experience trying to disassemble and antenna which has fused in places.  Definitely use one of the products - the Noalox comes in a bottle which looks like an old elmer's glue bottle, at least for one of the sizes (if that helps you find it)

Cheers,
Dan

Noalox from Lowes is what I have been using. It's meant for aluminum joints.
$9 for 4oz or so.
