I disagree. Sometimes you get nearly no orange peel on horizontal surfaces but I've been around very very good painters and they all say to expect orange peel. Clear coat gives some depth, but it's purpose is to add gloss and protection. Base color doesn't use an activator and is designed to bond with the clear coat, which is why you can't wait too long before putting clear on.A good spray painter will not get orange peel. The clear coat is to give the topcoat colour more depth.
