I knew I read about the Corvette people and hood vents from somewhere.
The clear coat didnt make the pattern it was the new coat of primer on top of the scuffed up clear coat. I was thinking a media blaster using some "softer" stuff like baking soda would be enough to remove it evenly. Or just make a week long project out of doing it by hand a few square inches a night with sand paper.
While their off I had the idea to see if CS vents fit, I`ll dig them out and see. I also have a set of Daytona vents I forgot I had, only have one drip pan for it though.
