OK here is a little stunt ya pull on someone who really blisters your paint.take a 3 inch strip of that styrofoam double sided tape and push thumb tacks through it, then take another piece of the tape and put it on the back of this, then stick the tape under the persons car door handle, when they go to open there car door they will have tacks in their finger tips, pretty cool huh?

or you can get "fiber glass reinforced bondo" (the stuff they use to do body work on cars). i suggest the long hair fiber glass reinforced stuff, put it on a piece of wax paper and add the curing solution, you now have like a few minutes be for this stuff is hard as a rock.put it on the car door handle of your firend’s car, repeat process for all other door handles.they wont be able to get in the vehicle
