[aprssig] I'm gonna drill....

[David Rush]

I need to do an antenna install for a tracker (see, it's APRS-related), 
and I'm tired of mucking around.  I've ordered an NMO mount and a hole 
saw, and the target vehicle has a nice, big, flat roof (and it's even 
made of metal, steel even).

Any tips on installing it?  I'm particularly concerned about doing 
whatever possible to ward off rust, including from the inside, so I 
don't want to leave any unprotected bare steel, if possible, even on the 
inside.

Tips?  Suggestions?
