Duh, I missed the trap oxidizers.
I thought you meant trap as in, "Wouldn't it be a good idea to get one of those cars and fix it up and drive it," only to find that the head is bad, a piston is shot, a cylinder is ruined, a rod is bent and just about everything that could bust during the rebuild will bust, leading you to spend way, way more money than you could ever possibly hope to recoup and you would have been much better off buying one in primo shape for $10K -$15K.
That's the kind of trap I though you meant.
