Rust Prevention- Best Method, Hot Oil?

Featured Replies

If you can find it, use what the Military used all thru WW2.

Its called cosmaline. I've seen stuff from the 40's opened up and still looked brand new.

I think I may have heard of that... must cause cancer or kill tree-frogs or something.. :rolleyes:

Fellow I worked with always poured his oil after changing it into all of his cracks and openings on his vehicles and they still look good after 25+ years.

You can buy cosmoline today in spray cans from industrial supply places. I know we have it over in the machine shop. But I don't think it will stop rust. I think it protects new metal, like dies and gun barrels.

I kinda thought about this too. When I change the oil, its hot. So if I pour it right into a sprayer, I can spray the rust and underbody some right there w/o warming the oil some other way. What does anybody think about the oil causing seperation of rusted metal? Sounds funny right? But I think it can happen, perhaps with any penatrant.

If the metal is RUSTY ENOUGH :eek: ....the rust is LITERALLY all that is holding it together sometimes!

SUPER RUSTY + PENETRANT = METAL FAILURE :dead:

I agree. But stuff that is not just rust holding rust together, that should be fine, and bye- bye rust. Right? messy, but solid old school tech.

It wont take rust down to good metal again....if thats what youre after.

BUT....it will keep rusty areas "in check" so they dont get worse :banana:

Yes yes- in check. Thats the route I want to go. This car was $400. Runs awesome, drives even better (you know). I just want the body to last almost as long as the drive train. I will try this method next time I change the oil.
