If the heat from the hair dryer is affecting the paint try hot water instead, dribble it onto the lettering and it should soften the glue just enough to easily remove them, you can then remove any left over residue with a product like de-solv-it which should be gentle enough not to affect the paint :winky:
Thanks buddy! sounds like it should work, il give it a go today or tomorrow and let you know how it goes :)
