When thinking about these materials, always consider the need to remove 
them. :)  3M 2228 and 33 are very good in this regard. Also UV.  Using a 
product (like plumber dope) away from its usual application requires 
answers to questions like this. :)

> What I don't like with the PL-259 is the lack of springs to keep the connection good at the screen side. All other connectors have some type of spring that ensure a good connection such as BNC and N. You have to tighten the PL-259 "well" in order to keep a good contact and there are no insurance they will losen up over time.

Tightening a UHF or N connector with pliers is part of mating it. If 
you're not doing that, you're not doing it right. I consider a quality 
UHF at least as robust as N (remember the migration problem).  I don't 
consider BNC a weatherproof connector, nor a good connector for 
permanent installations. Rather, I view it as one that is more suited 
for mating and un-mating, indoors, where systems are often being 
reconfigured.
