Great for removing residue off my Porsche
My Porsche had one of those "invisible" bras, probably put on in the factory in 2008.  We did not like the look and decided to remove it and it left a lot of residue as we started.  I bought this and followed the example in YouTube video by a professional detailer.  It worked perfectly and did not damage the car in any way.  only use metal, not headlights or the like.
