Ive found a big hole on the inner top rear quarter panel, behind where a wardrobe sits on a RHD, obviously from the roof being rotten above it and letting water down it. Only needs a cleanup and plating but its above the filler neck so im guessing its a tank removal scenario to do it? Not an urgent repair but if its an engine out, tank out job i'll need to budget some time in the future to tackle it *tut*
