I should have taken some pics, I tape off the door and fender panel right at the edge, after spraying paint/clear I then remove the tape. There is always a little lip of clear coat at the edge of the tape, I wet sand that 1/16" lip with 600, then tape the painted door jamb leaving that 1/16th" exposed, paint the rest of the panels and remove all the tape. Again, there is another lip of clear coat, this time I leave it until it is hard then with a nib file take most of it off and the rest of the blending happens with the various grits, 1200, 1500, 2000, during wet sanding and polishing.
It's a pain to be sure, but I find the final finish is better than spraying everything at the same time. The only time I did spray it all in one go I found a I ended up with drips and spots where I brushed up against the just sprayed surface. It also allows you the get complete coverage around the hinges from both sides, the factory sprayed it all in one go and the coverage on the front of the hinges was spotty due to the front fender being in the way.
