I had a politician in the cab recently and he was asking me about removing my 'MyTaxi' branding as he knew that I was soon to be re-branded to 'Free Now'.
He told me that he had stickers on his own car fer the last election, after the election he took off the stickers and using WD40 and a variety of other products he could not remove all the glue/residue, so he went to the 'Grand Prix' motor store in Cork and they gave him a glue removal gel which did the trick.
