Well as I've decided to keep the car for a few more years it goes in tomorrow for all four wings, doors, tailgate and roof panel to be resprayed. The wheel arches will be sand blasted to remove rust, there is no rot as i've diligently touched the arches up with Hammerite as and when required. Incidentally the Hammerite smoothrite silver paint is almost a perfect match for Brilliant Silver (MB744) paint. Should get it back beginning of next week so will post results. The bodyshop is local to me and comes recommended so fingers crossed.
