I have help usually from a couple guys I know who do radio installs for the 
railroad professionally and they just use good quality electrical tape 
rapped as you say on work ones and ham installs, this is repeaters and 
everything and I don't know of them having to fix their own work, other 
people's sometimes but not so much their own.
