Most manufacturers are using 3M double sided adhesive (tape) today. A piece of fishing line and a little patience will pretty much debadge anything these days.
I had the same thought about the rear badges.
The dental floss/fishing line side took a half hour to remove the adhesive (great stuff!) as most of it was left on the car. The badge on the other side was removed by heating with a hair drier and prying off with a plastic trim tool, about 10 bucks for a set at Harbor Freight - that side was clean in a fraction of the time. You could also use a plastic putty knife.
I wouldn't do it..but it is your car. He who pays, plays
Not that bad for the letters in the rear and the little fish on the sides. the C7 logo's are a different story. however. A member with an AW has posted his with the rear letters removed and it was a piece of cake.
