a dont see where all these problems come from if ure needing to paint a panel anywhere near the edge u just blend it on to the next panel and u will never get any problems and any sort of body shop should always offer a blend of the next panel or panels to keep them selfs rite and if u only want the whole panel painted edge to edge should tell u they,ll not guarentee the colour first .

by the looks of it the cabriolet has been painted imperial blue but uve just painted it edge to edge u would need to blend it on to the door and wing for them to be spot on

no need for a whole respray whoever said that .
