removing window mask scum

[adray]

i just painted a tamiya mini body, i've done several before but this time the window masks left a glue film on most of the window areas. i've tried rubbing alcohol and nail polish remover to no avail. anyone have any solutions?

If it's just tape residue another piece of tape will often times remove it. If it's really tough then Bolink Body wash.
