oiled their frame to prevent, stop rust. I was doing a fuel line under my Burb and, well..New England is catching up with my undercarriage. Despite my efforts of washing it down, undercoating, painting, etc, rust is taking its toll.
I've heard of people spraying oil on frames. Doesn't seem hard, just messy.
Does anyone on GTC have thoughts or experience on this?Gambling With Souls Since '79'

I haven't heard of it being done intentionally. My old '75 Jimmy lost the rear main seal on the way back from Alabama, after I bought it, and the frame is still pretty unaffected. We put in about a case of oil on the trip home.
I've been planning a treatment for my Burb, but haven't gotten to it yet. I'm going to use the rust inhibitor (POR15 is the name the comes to mind, but not the stuff I have) first, then paint over top. My frame isn't at all bad, just started to powder-up a little. I'll be following along to see what you come up with.

I have heard of doing that to the wheel wells but not the undercarriage. A local autobody shop suggested to a family member that in order to prevent rust that he should spray WD40 in the wheel well drain holes to prevent road salt from causing rust.

I use WD-40 ....about 1 to 2 cans on our old Toyota's undercarriage.....I coat everything 2 or 3 times over a period of 2 or 3
weeks before the winter sets in. The time lag gives each coat a chance to harden/stiffen up. I always ensure to get the brake
lines/fittings/gas lines/fittings......amazing how well our 1993 is holding up underneath ---still original brake lines, and no holes in the
floor...some of this is due to Toyota undercoating though. I also use the WD-40 in the wheel wells/door pillars/frames and
I ususally give them the 2 or 3 coats as well......Silverado Crew.....4.8 L

I live in Galveston Tx and salt air from Gulf of Mexico use to play hell with cars/trucks. My dad said ole timers would have under carriage of trucks sprayed with old motor oil then drive it for an hour on oyster shell roads. Seems the dust from shells somehow slowed down prevented rust. Had to do it every year.Charlie

Well..I ended up going with spraying oil. Although I did consider W-D40.
I used a cheap spray gun, drove her over a cheap tarp, and filled the cup with used motor oil.
I only did the inside of the frame rails. wasn't to messy, but not pleasant either.
I've heard this called farmer undercoating...
We'll see how it works I guess.
