try a heat gun and they should peel off but will leave the adhesive
glue behind, to remove the glue you can first try soap and water,
try a plastic edge to scrape off the adhesive, if not WD40 works great,
might take alot but it does work, used it so as to not scratch the
paint work. ALWAYS TEST A SMALL SPOT FIRST i am in the sign bus.
and remove alot of vinyl
