yeah. i've seen those. been meaning to get some. i have inflatable bladders and picks for car doors and slim jims, but these would make things so much easier on newer cars. (and before anyone says anything, I pick locks as a hobby and pop peoples cars open or houses or any lock for them if they ever need the service. to get a locksmith to do it can cost upward of $100 whereas i can save my friends and family that $100 with about 2 minutes of work)I think some of these corksoakers have something like this.
