As long as you don't mind spending a lot of time sanding and polishing it's dead easy getting a great finish from a rattle can. I wouldn't worry about orange peel because you're doing a lot of sanding anyway. Those dimples would be much deeper than any orange peel yo might get. Plus orange peel is a much bigger problem with acrylic lacquer and nitro. Not so much a problem with enamels which are self-leveling to a certain degree. With the Cabot's stuff I used it didn't have orange peel at all but it was sort of wavy probably because the surface underneath wasn't perfectly smooth as glass. I think your dimple problem is very similar.
Btw the fake walnut dashboard is now about 20 years old and it hasn't aged or yellowed at all. Not a scratch or mark anywhere.
