I finally got my 220 painted. Went back to Mercedes blue (903) and used acrylic enamal with hardener. Fortunately I was able to borrow a fresh air system.
Anyways. What time line do I follow for buffing, waxing ?

If you have organge peel you can color sand and buff right away.

If you wait for the paint to harden until you color sand, it will be next to impossible.

As far as waxing, I'd wait at least 3 months.
