WD40

[Dirtautoguy]

I have never used PB but I have noticed wd40 didn't seem to work very good for stuck stuff but it does for everything else, I even use it to wash grease and I've seen it used to get tar off of your hands before

Kroil is a great product. Beats PB IMHO.

 

I can't remember the last time I used WD40

Heres one that most people never thought of, I knew this old lady about 70ish she used WD-40 on here arthritic joints. She swore that it worked better than any drugs off the shelf. Go figure.

Use it for squeaky doors and as a dielectric in spark plug boots. Works great everytime.

I believe WD 40 was actually designed as an electrical contact maker. I kind of keep away from putting it on my truck because it catches dust. But it's good for lots of other things.

Dilectric? What do you mean and that sounds kinda funny it lubes metal joints haha maybe it works on human joints too lol

[00Silverado4x4]

Dielectric is kind of contradictory because its an insulator but works to keep the contacts clean and free of moisture. In my early mechanic years I worked on an old S-10. Changed plugs and truck ran like crap. My uncle told me to check it running at night for arching and spray WD-40 on all the boots that arch. Sure enough I had a few arching, plug and coil side of wires. Ever since whenever I check change plugs I spray some in there. The boot connects tight enough to make proper contact but WD-40 keeps out excess arching. Works same as the grease you can get at auto parts store.

I've heard of using grease but never wd40 for that maybe ill have to try it. So you can use it inside and outside the boot?

[00Silverado4x4]

I only use it on the inside personally I try to keep it off the outside since it will drip on the engine. I spray just enough to coat the inside.

Use the grease. Better in several ways

Lots of myths out there about the "amazing properties of WD40". Like most people I have a can in the garage, but I rarely use it. It does work great on my combination gate locks

wd 40 I dont even think its a penetrating oil . All good people with a wrench I know never say postive things about Wd40 they always mention a other product that works alot better.

[Morgan1986]

Wd40 is mainly just kerosene

[00Silverado4x4]

Yes it is a water diplsplacer and its best use I found is on squeaks other than boots. I still use PB or Liquid wrench if something is rusted fast.

^ If it's rusted fast I use a torch
