Randy,
Thats exactly how i do it and it only takes me 30 minutes to put on 4 numbers and the vintage stickers! The ones that are fun are the team stripes.
You have to cut them to fit the first time, Which Isn't easy! then get them lined up and contoured to the fenders. I noticed the dirt on the edge of the stickers when removed but nothing alittle z6 or z8 wouldn't take care of!
