Remove Bad Paint Job

[TJBegin]

Tried something new: two-tone model car. I used the modeling tape on the border but my technique obviously wasn't good. Two questions: (1) what's the right way to do this and (2) is there a way to remove the paint that bled past the border tape?

Hi!
You could check out this recent thread:

I had similar issue recently, but it was very small area on a figure, so I waited till it cured, carefully scraped the bleed back to the line, then painted over.
Cheers!
