So, I've got this old guitar (Ibanez GAX-somethingorother) that came to me with a quarter-size chip out of the finish on the edge. Being the crafty dude I am, I decided to sand it and repaint the thing. So, I sanded the body (120-150-180-220) down to the base coat, and proceeded to lacquer it up with some nice white car paint. Problem is, the color coat has some cracks and slits in the finish: Now, I haven't touched the paint yet with sandpaper...my plan is to do several more coats of white punctuated by 220-400 and 6 or 800 grit sandpapers (then do clear, pearl, or metalflake on top, with grits from 800 to 2000). Do you think that these slits are something that can be sanded out, or am I totally hosed on this one?
