oil spray suggestion

[WmWatt]

Spraying underside of car with used oil today, preparing for winter slush and chemicals, and discovered way to get oil inside at front of rear wheel well is to remove access panel to rear light bulbs. Shove wand of sprayer (I use and old garden sprayer) in there.

Umm, why don't you just use an oil base under coating?

How do I do that? Last time I changed it , it was big, but next day it was small.
Guess i'll look around in my settings.

Never tried diesel. I change my own oil so have the used oil. I think oil works because it seeps into the seams and can be sprayed into the holes in the box beams, inside the rear axle, and inside the body panels by removing the rubber body plugs I assume they are there for that purpose, ie you get good coverage. Rust comes from the inside so you need to get it in there. I spray inside the hatch and hood as well. Overflow and drips are caught by spreading old newspapers on the garage floor before starting, and kept off the garage wall by leaning plywood up against the far side of the car when spraying. I'm surprised how the oil clings to the body. It's still there next summer. Oil also attracts road dirt so I clean any nuts and bolts with a small wire brush and a rag before removing.

Never had any luck with FluidFilm. Supposed to contain lanolin oils but never stayed on for very long on any of the rust proofing jobs I did with it 15 years ago. Krown is professional rust-proofing 'oil' (it's not petroleum-based) and jobber price (I buy it by the case) is $7 a can or $12-15 at a hardware or automotive store. One aerosol can easily does a Festy. Used motor oil has all manner of contaminants in it and is 3rd class stuff for rust proofing because it softens electrical wires, seals, motor mounts and rubber mouldings. Even ATF is superior to motor oil in that regard.

I agree with Bert and plan to try canola oil next year. Meant to try it this year but forgot. It has to dilute to be thin enough to spray. Before the days of petroleum products it's ancestor, rapeseed oil, was used to lubricate steam powered machinery because it sticks to metal even when it's wet. It's also cheap, under $4 for 3L here, and 2L will do the Festiva. It isn't so good as a lubricant because, like all animal and vegetable oils, it breaks down more quickly than petroleum and loses it's lubricating ability. Yeah, and used motor oil is dirty, messy, and the little bit which drips off the car isn't great for the environment. I only drive the Festiva 2k-3k km a year and change the oil twice so my used oil is actually pretty clean. I also use it to oil bicycles, door hinges, and other things around the house.
