Do a search on this topic, I remember a thread a while back that was quite long. Some soak them in hot water, leave them out in the sun, any way to make them more flexible. I let them sit on the hood of my truck after going somewhere and let them get soft. I clean the number plates really good and then spray the sticky side of the background(yes sticky side) with windex(Makes them slip around a little) I then take a little squeegee(sp?) after there in place and get all of the windex out. After they dry they look great.
