there were alot of practices like that// when i was a kid my father knew a collector that would spray his cars waitng restoration down with deisel fuel to prevent further rust damage and these were hiend cars duesys lincolns caddys etc from the 20-30eras// and i also knew of people that sprayed the undersides with oil and or diesel// my favorite low tech way was during the summer when the road crews went to treat the back roads spraying recycled oil on the dirt roads you'd just get your buddies and a couple of quarts of beer at night and go rippen anound those oiltreated dirt roads fishtail away till you figured the chassis was coated or you ran out of beer// i used to love doin that with the big old merks buicks hudsons from the 50's nobody wanted them they were 10-20bucks each back then

theres alot of better safer and more effective alternatives nowadays
