Yeah, it sounds funny and I laughed about it myself...But I wonder how it would actually preform.
Back up a few months, a fellow who has every, ''Mechanics Illustrated'' magazine from the past 50 years was telling me he undercoats his Jeep with a mix of WD-40 and Marvel Mystery Oil twice a year and never gets rust. Fast Forward to this past week-end at a gun show. A dealer had several M-1 Carbines on his table caked in Cosmoline. I quipped to my brother, ''Pay $1,800 bucks for a Carbine and get two and a half pounds of free Cosmoline!..Wonder if I could undercoat my truck with this stuff...''
I googled, ''Cosmoline'' today and they still make the stuff...They even pay your state tax on it. They have several kinds and it comes in every imaginable container from a spray can to a 54 gal. drum. They even have one that, ''creeps'' for hard to get to places.
