To put it another way, I was once told that WD-40 is a degreaser...as opposed to a lubricant.

A buddy of mine swears my using regular vegetable oil on the underside of his cutting deck after it's cleaned off/scraped. Let it penetrate overnight. Certainly a LOT cheaper than Fluid Film...which is a marvelous product in its own right.
The stuff is amazing really. You know when a window get broken in a car and you duct tape a piece of plastic to cover it? Guess what removes the nasty glue the duct tape leaves behind? You got it, WD-40. I also use it to wipe down my electric guitars. Takes the dirt and dust right off and leaves them clean. You could wash a car with the stuff and it won't damage the paint!
 
wd-40 is not a lubricant or penetrating oil or rust preventative . It was developed to displace water/moisture. The main purpose to remove water from electrical devices. Such as spark plug wires and electrical connectors. The spokesperson for wd-40 stated this when Modern Marvels did a segment on wd-40. The name wd-40 comes from water displacement formula #40.
If you put this stuff on any fine piece of machinery (fishing reel, firearm) it will turn to a sticky varnish.
If you want a great penetrating oil to bust loose rusted or frozen fasteners try Kroil the oil that kreeps.
YOU got it! I was just throwing my one-off educated guess out there, but what you said is what I was going for. And it does leave a film, I've seen it happen. I have a friend who has ran a fishing reel repair business for years, and WD40 is one of his peeves because people give their reels a shot all the time but it actually puts a film over time and then he has to deal with it. Just another case of the amatuer fix screwing things up. (one time I tried to rebuild my engine myself and then hauled it to a mechanic 3/4 of the way through, boy did I fee sorry for him :hammerhead:) (no I didn't, he charged me appropriately :hammerhead:)

actually it says right on the can that WD-40:

-lubricates

-protects against rust and corrosion

-penetrates

-displaces moisture

Thanks Jason.:weightlifter:

I have seen the Modern Marvel segment many times now, but I also know what the can says. I think I'll take their word over anyone's here. It will take off road tar beautifully from your car's finish and not hurt the clearcote any. I have been doing that for 25 years or more, and it was also in the MM segment on WD-40 IIRC.
If you remove any decals from your machines that are worn and peeling (or just some of the rediculous warning labels that ruin the looks of your machine), it'll remove the adhesive left behind too, just as orangemower mentioned for the duct tape.

It is not a good lubricant for any firearm though as someone mentioned:nono:. It will gum up and just about totally ruin the innards of an otherwise fine firearm.
 
I use both wd-40 = cheaper. I use it for volume stuff cleaning hand tools etc. Fluid film is a little spendy but it last longer and I think it lubes a little better. I use It on battery terminals, trailer hitches and parts, trailer racks, and mowers but not under the decks.
 
One thing about WD-40... You do NOT want to spray it on anything in contact with rubber seals. It will dry them out. This is why so many boaters use "CRC" as a lubricant.
 
Well I sprayed fluid film on the unpainted parts of my mower. That's the last time I do that. The FF acts like crap magnet. Boeing T-9 at least dries like a wax candle and barely attracts one tenth crap that FF does.
 
FF works great on turf tracer deck rod pins to easily be adjusted. WD40 = (W)ater (D)isplacement formula #40 ..
 
At our water treatment plant we have tried many products to protect equipment from chlorine corrosion.
We use Fluid Flim and it works great. Since we started using it to coat all electrical outlets, plugs, and metal motor cases our loss from corrosion has dropped I know 50% or more. That's a lot when everything in water business is outrageously expensive.
 
The difference is that Fluid Film creates a crack like addiction that any purchaser can't resist. WD-40 doesn't do it.

Seriously though, fluid film has replaced WD-40 in our "shop". WD wears away about 60% quicker (if not more) than Fluid Film.

If I need a breaker, I break out the hot wrench and PB blaster. Sometimes I use FF with the hot wrench and works great too.

If you want to go cheap and make a great breaker, then use 50% turpentine and the other 50% with ATF fluid. That homemade mix is amazing.....

...
 
For protecting metal that is in constant contact with weather, Snow plow blades, deck pins on mowers, and chassis componets on cars, trucks and trailers I use fluid film. I still use pb blaster or wd 40 for a few things but for ultimate protection in the weather, fluid film beats all the other brands. Its worth the money because it out performs them!
 
Fluid Film stops rust on contact. It prevents rust on all metals from salts, fertilizers and moisture. It is non-conductive and protects electrical connections and battery terminals. It waterproofs and conditions leather work boots. It is a once a year vehicle undercoating. It keeps bugs from sticking on bumpers. It doesn't burn greenery on cutting devices and won't freeze.

There is literally no other product on the market like Fluid Film. It has almost unlimited applications because it won't harm paint, plastics or oil-resistant rubbers. It is so effective it is used by the World's Largest Equipment Manufacturers to protect equipment in storage and shipment.

If you haven't tried it and live in the US, just send me a PM today with your name and address for a free sample can. We even pay for shipping. That is how confident we are that once you try it you will be convinced of its effectiveness.

Only accurate answer I've seen yet. Sorry I'm trollin this old thread so hard, it's a pet peeve of mine so many people think they knew what wd-40's purpose is and they're not even close.. such dim bulbs
