I took the plastic/chrome letters off the sides of mine. First used fishing line and a hair dryer. Read that or saw that somewhere. What happens when you do it that way is a lot of the adhesive stays on the car. Then you waste ten minutes rubbing off the glue. So I say DO NOT USE FISHING LINE. Instead, get a hair dryer on high heat and at full blast start heating up the edge of one letter. After a minute take something plastic, credit card, spoon, whatever as long as it can't scratch the paint, and pry up the edge. You will see the adhesive pull off the car and stick to the letter. Keep the hair dryer on and direct it right where you are slowly lifting up. This way no adhesive is left on the car. It all comes off in one shot. Super easy. About 15 minutes and you'll have both sides done.
The look, I think, is way better. Super easy, start at any one spot, keep the heat blowing on it and all the adhesive comes off!
