HI, I am halfway through roof repairs to my GT6 which involved cutting out the top section of the windscreen frame due to corrosion. I intend to replace it with a section that I have removed from a Spitfire. I will need to weld a lip onto the spitfire screen frame in order to create the seamed joint with the roof skin. I will also need to remove and replace the front lip from the roofskin as it is partially corroded. At this stage in the repair, I have the option not to weld a lip onto the Spitfire screenframe and when I remove the front lip from the roof I could then weld the roofskin directly to the top screen surround and create a seamless joint. I do not intend to deseam the rest of the car, but I reckon that the front roof seam is probably the one seam that could be removed that will not alter the overall appearance of the car. I would appreciate your opinions on any aspect of this aspect of the repair and the various options to finish. Thank you.
