WD40 uses (If been posted before sorry)

[jpaul]

I have used it to keep things from rusting, it works for a while but then seems to promote more rust, I don't know why. Tested by spraying it in one of the four cylinders of a GS 750 that was sitting here, in about six months that one cylinder had some rust, the other three didn't.
Ed, I hope you have that tank on a bike full of gas sooner than that, or treat it with something else.

The additives that give WD-40 the water displacing properties actually remove the water by pulling it into solution. If you leave it be without using any additional rust protection, they will continue to absorb water out of the atmosphere until there is enough water present to come bac out of solution and cause the oxidation of the metal.

Whatever you do, do not use wd40in any lock cylinder. Wd will actual mildly etch brass parts. This etch plus the absorption of humidity inside of a lock is a bad combo .

Another issue with wd, is how it reacts with other "lubricants" Wd mixed with graphite, for instance.. . it makes the graphite bond to itself, not good inside of a lock where a thickness varience less than .0001mm can leave you out in the rain.

I have been a locksmith for many years, you will not find either Wd, or graphite in my work van.

I use Wd at home regularly, great cleaner, I wipe down all of my tools with it after a project.

I'm surprised nobody mentioned using WD-40 to remove gaskets from engine parts. I learned about it on ehow and tried it on my valve cover gasket. Just get a straight razor and it will take every last bit of gasket off and keep you from gouging the part.
