How long does it usually take for a vette to sit in the sun for the paint to be affected with "orange peel"?

 

I think you can get orange peel right away. Ive got a little in my clear coat I will be wet sanding it soon it showed up right away.

 

My understanding of orange peel is as follows:

Paint does not come down with orange peel. It either has it or it doesn't. A bad spray, one where the gun is too far away, will create orange peel. A way to correct this, is by wet-sanding.

After my car was painted, it looked like crap. Lots of orange peel and dust nibs. Then I wet sanded. Boom. It looks fine.

And orange peel is gone for good. It will not reappear, over time.

I hope this helped.
