i have removed the plastic door trims from my mk2 punto which is black, i did this because one of them was falling off, and i thought the car would look better without them, i used a hairdryer and heated them off pulling lightly. i have now got the double sided sticky gluey tape on my paint work, i have used a credit card sized piece of plastic to try and scrape it off without doing any damage but cant seem to get rid of it...any ideas?
