Persistence of Kroil

[Snakeoil]

It sounds like using Kroil is similar to seasoning an iron skillet with cooking oil. Leaves behind a non-stick coating of sorts. I've never tried it. And I'm a neophyte to casting anyway. I use Kroil. Used it for cleaning rifle barrels but tried Ed's Red and have been using that since. Save the Kroil for stubborn bolts.

With you, Snakeoil. Ed's Red for general cleaning @ $30 a gallon, but save the $30 an ounce Kroil for rusty stuff..

I have some Kroil and my can will last the rest of my life.
Cleaning is done with Hoppes- I don’t use much so a pint lasts me a decade or more. I can afford that.
Cast bullet only guns don’t get cleaned every outing so a little goes a long way.

I have a wide selection of solvents, lubes etc.
I use Rem Oil or 3in one Oil, for a quick rag down a barrel and a wipe down before putting my guns away. Kinda de carbon things.
For anything more on a cartridge gun, I get out the assortment of Hopes and the brush kit.
Cva breach plug grease or high temp wheel bearing red grease. For Breach plugs, nipples, and shot gun chokes.
Dawn to clean my muzzle loaders. Then 3 in one oil to coat them for storage.
Red grease for various rub places and threads on an AR. And some of my 22lrs.

PB Blaster, Marvel Mystery oil, and Kroil are generally used for unsticking things or lubing tools, according to application.
Use Marvel Mystery in all my air tools since the 80's. They all still work fine.

Wd 40 I use for its intended propose. Rust preventative on non moving, non interacting, steel parts.
Graphite and lithium for stoping squeaks.

Oh and Renaissance Wax for any wood.

Wd 40 I use for its intended propose. Rust preventative on non moving, non interacting, steel parts.

WD-40 is actually intended, as it's initials imply, to be a Water Displacing fluid. And I can attest to its effectveness in doing that. Back when I was young and poor, I had a Dodge van. I think it was a 1970. Winter arrived and with the wet, cold roads, the 318 in it started to run like a popcorn machine. I got home from work and pulled the hood off the engine and fired it up. It looked like the 4th of July. The plug wires were sparking and arcing like an old Frankenstein movie. Plug wires were expensive, WD-40 at the time was about $1.50 a can. I left the engine running and sprayed the plug wires. The sparks and arcs all disappeared and the engine settled down and ran smooth as an electric motor. I've been a fan of the stuff every since. It has its limitations. But it truly excels at its intended purpose.

I used it since for similar issues. My wife's cousin had a truck that say all winter as it was his plow truck. The barn was very damp. I went to start it and it ran like Jack Benny's Maxwell. It was a GM with those silly screws to hold the distributor cap on instead of latches. They were welded to the distributor body with corrosion. I sprayed WD-40 on the distributor, more like bathed it in WD-40 and it smoothed right out and plowed snow nicely for the rest of that winter.

The stuff used to be so cheap that they sold in in 3 packs and 6 packs at places like BJ's. Those days are gone now.

My great uncle always told me he used WD- 40. Prior to commercial sale. In the Navy to coat none painted missile parts with. As a water proof, salt resistant, static proof coating. To keep them from corroding in the salt air during transport.Thus the water displacement in the name.
He used it on everything metal that sat out side. Had all his outdoor electrical fixtures spayed down in the stuff too.

I like WD-40 for cleaning motorcycle chains before lubing with heavy motor oil.

I keep some Kroil around, good stuff for unsticking things.

Big fan of Ed's Red. I need to make up some more, but I picked up a big bottle of Hoppes at a yard sale a while back and have been using it.

WD-40 was a good thing back when it still had fish oils in it. [heck it was even good for fishing bait]
they really need to change the name to like WD-42 though.

Oh no, don't tell me they changed the formula?

I'm not a big fan of WD-40 in general and the stuff should never get close to a gun. Yes, I know it is intended to displace water, and that’s probably how it should be used. But it gets pressed into service for tasks it is not suited for. At best, it’s a mediocre lubricant and a terrible preservative.

PB Blaster and the other penetrating oils are handy because they come in a spray can. The big advantage of the aerosol penetrating oils is the ability to spray the oil places you cannot drip the oil onto. Almost any light oil will work as a penetrating oil, with ATF being the most ubiquitous. You can cut ATF with a little kerosene if you need to.

Kroil is great stuff as both a penetrating oil and a gun care product. I use it when cleaning barrels that shoot lead projectiles.
Hoppes #9, or any of the similar products with ammonia, are good for cleaning bores after shooting jacketed bullets.

Oh no, don't tell me they changed the formula?

Today's formula, as I understand it, is basically 90% Stoddard solvent and 10% wax (paraffin)...and when you know that's what you are spraying onto whatever, is when you know why it will or will not work.

Marvel Mystery oil - a story about that stuff. Worked with a Mech Eng that would put a quart in his PU engine, run it for a while, then change oil. Well, one time a rod exited the side of the block so he changed his way. He wouldn't buy a GM auto, claimed the metal alloy used for the body actually (EMF) corroded it's self. She's got a relative that developed a lube for aircraft rivets (WWII ish). Made a bundle from that. IIRC he added something to WD40. Owned a company making special auto lubes. WD40 is good for a small engine starting fluid.

WD-40's claim to fame is the massive distribution network associated with the stuff.

It can be found in every convenience store, general store, small grocery store, big grocery store, big box store, farm supply store and auto parts store in America. Although it can be purchased in non-aerosol form, I suspect the vast majority of it is sold in aerosol cans. The stuff isn’t great but it sure is ubiquitous.

I use WD40 for cleaning my lathe and mill. I consider it more of a solvent and this point. I follow up with dry rags then way oil.

 

[fiver]

i use it mostly as a fire starter.

That may be the best use for that product.........
