I knew a guy once who made his own product for spraying his cars with.I believe he used chain saw oil and wd40. I don't know what the ratio was,just curious if any body here made their own,and what did they use.

I don't know what you are wanting to spray with this concoction but I do know WD40 is not a rust preventative.

Well Cletis I think you better rephrase that statement just a little on the WD-40.
WD was invented to displace water or moisture on missle products which in a sence does prevent moisture or rusting to a degree.
But I will have to agree to disagree that it doesn't prevent rust totaly. If you want something to stop rust forming then the best thing is good metal prepration then metal prep 79 along with a good primer and paint to keep rust from forming. There are many many things that you can do to prevent rust.
One is to encapsulate it to prevent oxygen from getting to the metal causing rusting from moisture.

When I lived in Detroit I knew a guy who mixed STP and kerosene and used tubes and whatnot to spray that concoction into all the hidden areas of his cars as a rustproofing much like the rustproofing services of today.

What happens is that the kerosene evaporates leaving a film of STP on everything. Despite the horrible road conditions because of the amount of salt used to deal with the snow and ice, his cars were completely rust free.

Now mind you, he didn't use this on the exterior of the car only hidden areas inside pillars, fenders, doors, etc. And this in addition to the undercoating that was a common option in those days.

WD-40 is a solvent and will get moisture and most greasy stuff off. But, that just leaves you with squeaky clean, unprotected parts. After the parts are dryed from DW-40 then rust prevention can be addressed or the parts will just start to collect moisture and rust again. If you sprayed them together the WD-40 would be washing it off as you were spraying.

Added note: Starting a stored engine and not driving it is the worst you can do. The heat attracts moisture and rust forms. If you drive it and get it up to operating temps, you boil out the water and then it is coated with oil for protection. The worst offenders are airplane owners and motorcycle owners. Air cooled, but the same holds true. Temp of the water in the cooling system is only that, the real heat is the exhaust gas temps where the temps reach 280-300 degrees, hense boiling out the moisture. That's why warming it up til the thermostat opens is not nearly enough.

Does anyone here have any experience with Ospho? It's a rust treatment with a very light consistency, almost like water. The active ingredient is phosphoric acid, the same ingredient used in naval jelly, and most commerical rust removers. The makers claim that it chemically neutralizes rust, leaving a black coating that can be primed and painted.

Thanks...

Get the generic phosphoric acid. With Ospho you are basically paying for a name brand. I have purchased it when I didn't want to drive another 30 miles to get the generic. I didn't see any advantage to the added ingredients, what ever they may be, in their formula. And it cost about $10 a gallon more than generic. And yes, the phosphoric acid works great to de-rust parts.
