I wire corp. jets in my spare time (the home projects are my full time job). 
Aircraft Wiring Practices (read: FAA 4130) state that terminations should be 
either crimped or soldered, but never both. Our crimp type butt splices are 
sealed with a heat-shrink sleve, but ring terminals are just higher quality 
auto type. The only time we use heat shrink is on un-insulated ring terminals 
to prevent acring. We use mostly PTFE insulated wire throughout the aircraft. 
Some high temp/stress locations (engine nacels, wheel wells) require a 
fiberglass braided insulation and nickle plated copper strands. AC wire 
cannot have fewer that 19 strands. Waytek Wire and Del-City have a good 
selection of quality wire if you want to buy in bulk. Waytek only sells to 
businesses, I think. That is what keeps those jets in the air, FWIW.
