DARRIN..... We just put on the last clear coat today on our EN-7237. we used 1 coat primer after sanding down to bare metal with a finishing sander, then 3 color coats, hand-sanding w/1000 grit between each coat(lightly) and 2 clear coats. Then we'll wax it. So far so good, but the key word here is patience!
EDIT-- forgot to mention, we used Rustoleum primer, paint and clearcoat, don't mix the brands of paint your using.
