hello. just had my car looked at for rust bubbling. the guy said it was a stone chip so i questioned it and he changed his mind and said it must have been painted, because he's only seen it happen on cars that have been painted. when i told him to my knowledge it has never been in an accident, he then said "were not a bodyshop, so i wouldnt really know". so why is he looking at my car?

what do i do now then?
fork out for some independent bodyshop to give me there opinion? i dont quite know where to go from here, but i want it sorted and i dont think i should have to pay for it.
you lot have any ideas?
any previous experience with volkswagen that might help guide me?
