Someone told me white spirit would do the trick,... but I'm struggling!!
I've gotten the lettering off no probs with a scraper (carefully!) but the glue left behind just won't budge!! I'm scrubbing with white spirit, heating it with a hairdryer, even tried a bit of T-cut. Its shifting very very slowly,.. but seiously, its going to take me all week if I carry on like this!!!
Any advice?
