Raced a 92 Vette before the Cobra--so I've got about a decade's worth of experience with static cling...

Assolutely clean and wax the area. Also, while more difficult to work with--I get the thinnest stuff I can find so it lays down as flat as possible. Take your time and use water to put them on and get every bubble out--smooth the edges down with finger. Have a nice flat surface to put them on when you're not using them--after you clean them thoroughly. I use some of my kids' school project boards and just make a sandwich with them to prevent any harm. Be careful when it's warm on the sun is shining bright when you put them on--do not pull or you will stretch them out--very noticeable on meatballs.

I've used them in dusty autocrosses and high speed track work--Vette went up to 150 mph with no problems despite the seam and curve of the body--much worse than the Cobra.
