600 is too fine for a good mechanical bond...400 is about tops...also, when you pull the tape, pull it at an angle (30 to 45 deg), down upon itself...that would help eliminate some chipping. The bleed thru on the color separation line can happen if u don't press the tape down firmly enough...a fingernail ran along the edge a few times can help that..
all in all, it looks good, a little buffing will cut the peel down...
unless you plan to run it thru barrett Jackson, with a little touch up, you should be just fine
Maybe a black boot stripe along the color line will hide any prior sins...
...or just re-tape the red line a fraction above the old line, and another red coat.
