My friend took his Gransport to a specialist paint shop to enquire about having some small rust spots under a light cluster treated. He was advised that it required the rear bumper to be removed but that this could take 4 hours or more, with the labour costs that entails. They said an Aston Martin they’d had in had taken 6 hours to remove the bumper versus 8 hours book advice and similar to replace. Does anyone have experience of how hard the rear bumper is to remove and replace time-wise?? Thanks.
