You can get heatshrink crimp terminals with (stuff like) hot glue in the h/s section for sealing duties.
I've heard lots about soldered cables in cars suffering from vibration stress fractures, but the home made soldered loom in my '72 series 3 land rover is still working fine 10 years on... Maybe real leaded solder is the secret.
Edit: All of the 'lots' I've heard has never been first hand experience, always more like "Dave down the pub said" - I'm not denying it happens (and I've seen it first hand in aviation situations) but I don't believe it's as big a problem as is made out in automotive use.
