I painted my NSX using the information given on how to paint model car bodies on this site. The main colour was Tamiya Metallic Blue and a Semi Gloss Black Roof. I gave the car 4 coats with the first one being light and got the orange peel effect you guys mentioned. But is the orange peel effect supposed to be like rough spots on the paint? I am getting a texture like rough sandpaper in small areas on the paint after I am finished spraying. I left the paint for a good week before I started the cutting and polishing so it was nice and hard. I started polishing and checking like you guys mentioned but the paint didn't get as smooth as I thought it would and I eventually rubbed down to the primer underneath. This has happened twice now and I am going to respray the car and try again. Is the car supposed to be mirror shiny and smooth or will it still have tiny lumps and bumps in it? Also when I polish I notice that the white compound stays in rough patches of the paint. Any tips on how to fix these problem will be greatly appreciated.
