Although WD-40 is one of those products with 1000s uses, 3 are the most important to me.
1) When your car will not start on rainy days, or after going through a puddle: Open the hood, spray the spark plug wires, spark plugs, and ignition coil liberally with WD-40. IMPORTANT: Wait 5 minutes. Your car will start. Same with boat engines. WD-40 physically displaces moisture. YOU SHOULD HAVE A 3OZ CAN OF WD-40 IN YOUR GLOVE COMPARTMENT---JUST IN CASE.
For the following, you need a big can:
2) WD-40 is instant repair for awning windows which will not lock shut, or will not open, or for stuck or stiff windows of any type.
3) WD-40 is instant repair for anything that should move but doesn't, such as garden clippers.
4) WD-40 can be used as an "engine starter" for hard-to-start gasoline engines. Take off the air filter (of your lawn mower, etc) spray some WD-40 into the carburetor and start it. Warning--in this case the WD-40 mist is flammable---so be sure that you are out-of-doors in an open space (not a garage).
5) WD-40 is wonderful for removing non-water-soluble glue---for example price labels and the gummy mess left after you've tried to peel off a label. Spray on, wait 5 minutes and then rub off with a cotton cloth.
CAVEATS
WD-40 does evaporate eventually, so it isn't an ideal long-term solution to anything. WD-40 is too thin to provide much protection against the wear of moving parts. It is a petroleum-base oil, so it isn't good for rubber (petroleum oil and grease dissolve into rubber, weakening it). In fact, the reason that you can use it on automotive engines without causing damage to rubber components is that by the time the engine has gotten up to operating temperature, nearly all the WD-40 has evaporated.
LONG TERM SOLUTIONS
>> For lubricating rubber ALWAYS use silicon spray or silicon grease
>> A long term solution for a car that won't start in wet weather is to smear silicon grease on the spark plug wires, paying special attention to the spark plug, ignition, and distributor boots.
>> A long term solution for awning windows is to lubricate each moving part with automotive grease or silicon grease. Automotive grease provides better lubrication, but attracts dirt, eventually becoming a gritty paste which is actually damaging to soft moving surfaces (such as painted wood or soft aluminum of sliding doors and windows). So, use petroleum oil and grease on hard metal; silicon grease on painted wood or soft aluminum. For sliding doors, always use a silicon spray. Yes, I know lubricating every moving part of an awning window is very time consuming---honestly, I usually give a quick spray of WD-40 and forget it.
>> To protect things (such as the moving blades of hedge-trimmers) from wear, petroleum grease is a must. But a light spray of WD-40 will loosen up tight blades to make them easier to grease
>> A long term solution for preventing rust on your tools and to keep them lubricated is also automotive oil, automotive grease, or silicon grease or silicon spray grease. The automotive oil and grease are time-consuming to apply, and are "greasy", but protect best. If you lightly spray your tools with WD-40 every time you put them away, and they always work when you need them, that's good enough. If you rarely spray your tools before putting them away, and you always have to heavily spray them with WD-40 when you want to use them, that is NOT good enough.
>> Silicon spray will probably protect things like fishing gear better than WD-40, but will not displace moisture to begin with. So, if fast-and-dirty is good enough for you, then WD-40 is good enough. If you carefully clean and dry your fishing gear before putting it away, silicon spray will protect it better.
>> If you need to water-proof electrical connections (such as those of a basement sump-pump, or on a boat), keeping them soaked with WD-40 is a poor solution. For one thing most petroleum products can conduct electricity and burn. Silicon grease does not conduct electricity, does not evaporate, and does not burn. If you want something even more permanent, use silicon glue to waterproof the connections. Actually, if the connections are at least semi-permanent, silicon glue is the best way to waterproof most connections.
