mountainC4, please post about your install experience after you make a choice. i'm thinking about a new front bumper cover for the C4S, then will need protection. had 3M on my previous car (boxsterS) and no problems. looks like venture shield is the next crank of the technology.

 

An excellent installer located in the Chicagoland area is Robert Murphy at Design Shielding 847-903-1019. I don't know if you guys are picky but I know you gotta be careful who you use to do this type of work. Ya know the problem is people don't care about other peoples cars as much as if is was their own... so ask for background when searching for the right guy.
