Fish Eyes look like little craters on the moon where the paint pulls away from the center. (Looks well, like a fish eye and hence the name). Fish eyes occur immediately upon spraying. Fish eyes are caused by contamination of the surface you are spraying. Water, oil and silicone are the three major culprits. Also, if you leave the wax and grease remover on too long before wiping it off, it can cause fisheyes. When you wetsand out imperfections in the basecoat, sometimes there will be traces of water left causing the problem

that fish eyes, but i suspect your thinking "orange peel"

heres a link to some of the causes (its for wood finnishing, but it still applys http://www.furniturefinishwizard.com/orangepeel.htm

Thats it orange peel.. That article was very helpful. Last car I painted, that got the orange peel, was painted on like a 80* day with a slight wind in a open garage. The article stated that with a lot of open air the paint will dry before it flows together. I was thinking that if i sealed off the garage with large plastice over the overhead door this will help a lot. Also, it will be a 70* day this weekend adding to the equation of helping the paint flow together.

What grit of sand paper do you advise on using before painting? Wet or dry sand? etc etc.

dry sand is fine, 600- 800 grit for final sanding before base coat
