RNK,
My Cobra is at Kens now. I'm repainting it due to a bunch of chips running different tires that throw too many rocks and paint from a former paint job that did not hold up, painted in 2001. I decided to have Ken give it a go this time around.
I'm doing the 3M paint-on guard over the entire nose of my Cobra, and on the rear fenders starting just behind the doors - no messing around this time after too many chips on the first paint job. All the paint is being removed, prepped, and redone. If I had Ken paint it the first time, I would not be having to re-do it all over again.
Here is a custom car we did a while back (a.k.a Lister COOX), photo taken at Ken's shop just after paint. I had Ken paint the entire nose with paint on chip guard on it. Its hard to see the line, but in any case it works. This car has been on the road for a few years now and there are no chips on the front end. The same will get done on my Cobra.
