Hi, got loads of pics in boxes somewhere. Before the time of digital cameras so they are hard copies I will have to get some scanned of whatever it is you do with them. (old bugger me).
From the pics it looks like it was originally made in two halves upper and lower and bonded together. It looks like it has split along the "join line" on the front edge/lip. Think if it was mine I would do patch repairs as you say to get the strength back, but I would then wet lay/skin the bottom "lip" in one piece of carbon.( just up to where its painted white now) Paint everything above that and then clear coat the whole thing. At least then you would have some "visible" carbon.
Regards Warren
