I remember a while ago someone recommneded a lubricant thats better than wd40 because they said it was not water based and wouldn't dry out the way wd40 does. I can't remember what it was called though, would that be the silicone based liquid wrench? or maybe PB blaster? I'm guessing Not PB blaster since it eats away rust, so probably silicone liquid wrench?

 

Meh, all works the same to me.

 

It depends; it'd be really helpful if you tell us what you want to do.

WD40 is not water based; it evaporates away because it's mostly a solvent and what oil is in there (about 20% by volume) is a very light oil. PB Blaster is similar, it doesn't "eat away" rust; its thin viscosity means it can "wick" into the threads of a rusted nut/bolt and give you a chance to break it free. Neither are any good as long term lubricants; for that I'd just use motor oil or ATF.

 

for example, the front door of my apartment doesn't shut close all the way and i have to pull it shut - i put some wd40 on the hinges and around the door lock/jam and it worked perfectly for a couple weeks, now again the problem has come.

same with my friends car, you pull the hood release and the hood doesn't pop properly, we put some wd40 and it worked perfectly for a few weeks, now again the problem is back.

 

Silicone is very slippery and should be waterproof...that might be what you're looking for. Also silicone is not petroleum based so it won't evaporate.

 

yeah i think that's what I was recommended a while ago when I asked a guy about lube for power window tracks on an old camaro (the window kept getting stuck)

 

Snot is better than WD40, followed by spit.

Seriously, WD40 is a better solvent than it is a lube.

 

WD40 isn't really a lubricant. The name stands for "Water Displacement" and 40 is the number of formulas they went through to get the best one.

That's why your door isn't working as well now. After WD40 you need to lube things

 

I use Liquid Wrench Spray Silicone for the door and trunk weatherstripping. I spray the silicone on a cloth and then apply it to the rubber. For the rubber under the hood, I do not use it, because I don't want the silicone vapors to get sucked into the air intake and foul the sensors. For under the hood, I use a rubber cleaner.

WD-40 is death on rubber because of all the petroleum distillates it contains.

 

Ah, geez.

WD-40 is NOT a lubricant - that's why it doesn't seem to work long. It does some things really well...but I would never use it when I needed a lubricant.

If you normally use WD-40 as a lubricant, try white lithium.
