Just an idea only - has anyone tried using prepsol? If it was fresh I would think it would work no probs but I would be interested in a test spot to see if it worked??? 
I think prepsol is the same product as shellite,good for removing wax,silicans etc for pre painting but I dont think it would be potent enough to remove paint.
Not sure. I think it has more strength than shellite...
I've just been on the phone to my spray painter mate.....He reckons prepsol may be worth a try, but most likely will not do much. He seems to think thinners should remove it (depending on type of paint) BUT could also take out paint from underneith?
Are you planning to try to recover it to make a stencil?
