Jeff - Thanks for that, I look forward to seeing that progress. I have done repairs and restored an MGB however all of that was metal based and for some reason I am nervous about the finish on Fibreglass and my OCD nature I have spent too many hours already on shaping the roof alone!
I am currently at the prep stage with my MX250, I am using all Upol based products for the prepping stage.
You are lucky you are too far away for me to 'drop in' on, otherwise I think I would be dropping in to see your progress in the flesh!
