Ok so I have resisted doing the tub as its a huge amount of work... Ive made moulds and composite panels for the Front & rear clams, doors and front wings.... I wrapped the roof and window panels on the Tub which looked ok but not perfect and there was clearly no benefit other than cosmetics and it never really sat right with me.... I felt I had left the car unfinished!

next step was to go over the 2 coats of Gel with a thin coupling coat using glass tissue... this allows the custard coat to bond to the Gel coat as they use a different chemical composition.
