I have some much cheaper alternatives that still offer the same longevity as the method recommended in this thread.
I use a very small bit of solder inside my crimp terminals (but not enough to run down and stiffen the wire). This offers the same benefit and longevity of tinned marine grade wire and connectors, but with much cheaper automotive grade components.
Also- if I'm out of adhesive lined heatshrink, or it's too expensive you can obtain the same benefit by thoroughly coating the terminal in dielectric grease or petroleum jelly before applying the heatshrink. This will displace any free volume inside the connector, and make it impossible for water or oxygen to intrude.
For those of us living inland it's impossible to purchase marine grade electronics on short notice, so improvisation is sometimes required. My connections done with regular auto parts store components have held up long-term in saltwater environments done this way.
