Painting The window trim

Could you guys tell me whats the best way to paint the window lines?
Also when i was painting seats, the paint went under masking tape, and left dirty work.

I cant find it. Could you please post the link? :)

Simply put, spray clear coat over the tape first, before any other color. It'll seal the gaps.
