Deb,
I liked these so well, I got some for mine. I'm only using two (next to the GM logo). I showed these to a friend who runs a used car lot and also does a lot of detailling. He said to remove them every once in a while to let the paint breathe, or they could cause the paint to bubble. Can you ask Henry his opinion? Thanks.

 

James...that's why I went with the magnetic...so they could be easily removed and Henry was in total agreement. Had a problem with my 84 Honda that had a bra on it...paint fade and damage can also occur if not removed occasionally.

I'm sure a car can be over-chromed....but we've sure got a pretty big space to work with...so if it's done tastefully...I think it's great.
