I just bought factory effex stickers for my drz. I drained all the gas to store in my basement, that is heated and not damp. The next two days I looked at it and saw the grafix some how pulled back and a 6x1" oval appeared. It was not against anything. So then I stuck it back on. The next week I checked again and it was back on both sides. So I put it back, but this time I took off the tank cap. Has this happened to anyone else?
