Mercifully, during GW1 our VC10Ks escaped being painted with graffitti by amateurs with rattle-cans. Although at Muharraq, the rather inappropriate logo "The Empire Strikes Back" was applied to some, together with a large 'BP' emblem, but at least a professional was hired to do the work.
I don't know why there was such enthusiasm for so-called 'nose art' on RAF aircraft. To be honest, most of it was pretty dire and not a patch on the art applied by the Americans to their aircraft.
