As mentioned above, dip the bullets in silicone grease or similar before re-fitting them and you'll be fine for years.
Regarding soldering, its generally frowned up on. I design motorsport chassis looms and everything is crimped. Solder can create brittle weak points that will eventually fail. Once you've got the right too, crimping is also easier!

I only ever solder the ends (where the wire sticks through the bullet connector) after crimping, to keep the wire in place. Mostly if I think the wire is a bit thin for the connector.
Best wishes,
Mike.

Nothing wrong with soldering if it's done correctly, but crimping is more easily automated and quicker in a production situation. Plus you don't have to buy solder, and deal with flux and fume extraction
Trouble is I've seen too many DIY jobs where someone has used the wrong crimping tool or connector for the cable size.
There are several soldered connections on my Moggy, which are still going strong after 50+ years! However, I have seen some Lucas connectors that were neither soldered or crimped, but actually resistance welded

If your connectors are badly corroded cut them out and replace
If they are just tight you can warm up with a hot air gun and slide off or slit the PVC or rubber sleeve and pry the side of the connector free from the bullet with a small screwdriver or blade.
A great variety of kits for replacement parts and various tools can be bought here:

I generally prefer solder bullets and the tinned type such as those made by Ripaults.
or these which I think are brass type

Just a couple of things:
WD-40 will not attack rubber but is not a great conductor either. It does tend to go 'sticky' after a time so is not the best for door locks or ratchet screwdrivers.
Rubber grease (I use Castrol GRR) will keep water out but again is no great conductor.
Metal based high temperature 'never seize' is a pretty good conductor, corrosion preventative and very good on the horn slip ring. Wipe away excess at each location.
