There have already been many external vinyl wraps on LU trains and buses

object to a reputable sponsor paying handsomely to have all internal panels
in a train covered in its ads.

That already happens to a degree on the W&C line - adverts for financial firm
du jour covering every advertising space on the whole train.

Vinyl wrapping other parts is probably possible, as long as they don't
obscure or impede safety functions (eg visibilty down the carriage or the
prominence of safety notices).
