I've just bought an Early Bay and the roof is in good condition. No splits and chips or bad paint jobs but, the Dorma roof could do with a clean outside. It's a little dull with some light grey spots. I've tried Feracla but it gave it a shinier finish without really cleaning the engrained dirt off. The best GRP cleaners seem to be boat hull cleaners but these are brush on/ wash of acid based products so obviously not going to use those over paint!! I certainly don't want to paint it as the van is pretty original. The roof is not horrendous but there's room to improve it.
