well of course you still have some "contamination" in the paint. It doesn't matter what you do, if you get a part or a whole car repainted, there's going to be dirt in the paint. That's just something that's always going to happen. That's why they invented the buffer. But it looks pretty good. And about the masking...you get what you pay for. But the car looks decent from what I can see so far. You need to get your trunked lined up, I mean...nobody's is perfect...but whenever I see a misaligned body panel I cringe. Keep up the decent work.
