try a soft wire brush with 92% alcohol on it just hit it in the spots you want to remove paint.

so what you do is paint the 1st logo clear coat it paint 2nd logo cleat coat let all dry 24hr.

take wire brush dip in alcohol hit the logo where you want to remove it.

i would try it on some styrene 1st to get it down but it works well i use this for rust under paint on ork stuff all the time
