I’ve had no problems as long as the surface is very clean and you put them on the car at least 48hrs before you plan and driving at high speed. I know this from experience… For the last event I attended, I put my meatballs on my car when it was “somewhat” dusty about 20hrs prior to running. My first lap at 140mph the one on the bonnet flew-off (scared the crap out of me by the way) and the next lap the one on the boot launched (that one made me laugh). Needless to say I’m on my seconded set of m-balls and will follow the directions better.

It’s also a good idea to let the car sit in the sun after you apply them.
