Over my head…

I feel better, thank you, maybe I was overthinking
Well, it ain't ever gonna be straight as a metal roof so I wouldn't worry with it. I think it looks fine! I did one when I was a kid on an old Triumph Spitfire and it had a few wrinkles but they came almost all out after it had been in the sun a while. I bet it'll get better.....but either way, have fun with it!
