my friend had the whole front end of his nismo 350 CB'd back when he first got it. they did the entire hood, both front fenders, mirrors, front clip, and a-pillars (all the way back to the hatch since they are one piece). it wasn't cheap but there aren't any lines on it at all and it's hard to see that it's there. having said that, it bubbled up a little in a couple places that were not fixable without replacement. also, along the bottom edge of the front bumper there are couple places where it wrinkled up slightly. the guy tried to correct this and it helped a little but you can still see where the wrinkles were. you can kind of see them along the bottom edge of the red, right where it changes to gray on the front bumper here:
notice you don't see any lines (and yes, they would show up if the entire section wasn't done)
