For door hinges, the grease gun is best, but for just about everything else:

Your local motorcycle shop will sell you an aerosol can of Chain and Cable Lubricant - grease dissolved in carrier solvent. Works on door latches, key locks (a bit messy), hood and trunk hinges and latches, gas fill doors and locks, window mechanisms, your garage door . . . everything that moves.

The motorcycle shop will also sell you a small clamp that will fit on and seal the end of a cable and will accept the spray tube that comes with the can of lubricant. This will alow you to force grease down the full length of the cable. I do all the cables on every car I buy (throttle, clutch, hood latch, emergency brake) and repeat every 10 years or so. I've run cables up to 25 years and have never replaced a cable except for one emergency brake cable that got nailed by road debris. The grease does not seem to attack the polymer sleeve found on the inner metal cable in some cables.

I purchased some white grease in an aerosol can from the Toyota dealer once. It was supposedly for door hinges. I didn't like it. It didn't seem to penetrate well and it dried up and blew/washed away after a few months.
