you going to laugh but i found my black and decker heat gun would work.
i would heat it up untill a bit of it was bubbling then wiped it with a thick towel (thick because it was HOT!) it smeared a bit but once you get the majority off denatured alcohol woiuld clean the last little bit up.
if you soak a towel with denatured alcohol and press it to the tape it would turn it to gel then you can pick it off.
it took me 45 minutes per side...good music, cold beer, and a nice chair to sit on.
