Squeaky/Noisy /Rattle Exige Roof -58 plate

[claypole 7]

Ive have owned a few exige over the years, but never experienced a roof this noisy, its seems to squeak and rattle all the time. Its already been back to Lotus exeter once, but still no joy, this is totally spoiling the experience beacuse its so intrusive.I understand Lotus have tried silicone lube spray etc, but surely I can't be the only one to suffer. I would really appreciate any advice or comments.
