Are you not selling the engines? Or already sold.

I don't know how critical dope is to 4wd, but it's critical to 2wd. What's stopping someone from using something that has no smell or residue? Or from applying it away from prying eyes in between races? And if they have no tech for anything else, then how do they propose to tech this? What, gestapo spot checks because someone does a little too well? I'm real unhappy about this crap.
