wow, ya, there is a bit of peel there. I think you have to play around with your gun adjustments. What air pressure did you shoot at? Also did you reduce the paint correctly if it called for it. So many factors can cause orange peel from your gun adjustment, pressure and fluid, paint viscosity, how far you are from the surface, ect. Or even the proper tip and aircap in the gun you are using. Could also be too fast a solvent or hardener not giving proper flow. Hard to say what the cause is in your case. Good thing you practiced before doing the car, smart man. Keep playing around with your gun settings and distance, speed and pressure and get it shooting better and be set up before you start on the car itself. Then only minor adjustments may be needed. As far as wetsanding and buffing orange peel in an acrylic enamel, if a solid color and a hardener was added, it normally can be, If not then its pretty much what you spray is what you got without clear on top. Even if cleared you would want it smoother then that. I think its repaint, that looks like quite a bit of orange peel to sand and buff out. Heres a link to orange peel and causes. Good luck on try 2.
