How good is the finish close up?
Its not bad, some bits (80% of the shell) I have got a really nice smooth finish, and a couple of bits the finish isn't so good, but that was down to bad tecnique by me, made worse beacuse it was a roasting hot day when I did the 1st coat.
(its covered in sorage dust at the mo, should be clean again in a week or 2 so I grab some pic's then).
Sanding wise, every other coat is what I read, and for the 1st 2 coats I would def go with that (to get the coverage), but I would then adjust that on how bad/good your orange peel is. I would prob knock back any oragne peel/ imperfections between coats if your going for a mirror finish
