As I was saying......! Roberto Rodas has (at last) finished the damage to my hull caused by Cobb's and, while he was putting the finishing touches, I asked him to have a look at the pillars of my windscreen. His advice was that they are actually plastic, that the damage is sun based and that the fix is to obtain new ones and he can fit them, circa £1000.00!
Going back to my original question, I noticed a thread on the Jeanneau facebook forum about a guy who had the pillars etc wrapped on his boat by a firm in Southampton who specialised in boats. I thought it would not be a goer with the travelling but gave them a call anyway. Seems he is doing a job for the RNLI on the 16th January (handy) and could do mine at the same time and the price is not prohibitive so hopefully, job done. As I have bought G3 paste, I will just give it a try first but I'm not hopeful.
Terry.
