DON'T use aircraft stripper on composites... EVER.... it's been known to soften or delaminate composites... unless it is the stuff that is specifically designed for composites.. either way, it will remove ALL of the paint.... but honestly, sandpaper will be your best friend.. but will require a repaint... if you can't find an edge on the graphics, it's cleared over... if you can find an edge, make sure it isn't in fact vinyl(try to scrape it with a razor blade, vinyl will peel)... but if they are in fact painted, i'd sand and repaint...
