..super weathering J-L..interested to read you have used 'real' leaves ...I have been experimenting with 'real' grass this weekend ...the fine stuff that clogs up the bottom of the strimmer - once dried and hardened - is excellent for this purpose...

and you should consider the 'Marmite' technique for paint chipping as detailed in a recent magazine article (MMM magazine I think..) ...oops, guess you don't get Marmite in France ...
