I think I need to go over some of the parts again.
Main trouble is that some is applied too thin.Will give the the road wheels a second go and see what happens.The idlers I am happy with and have since painted on the black tyres.
Unfortunately the pictures do not really give a true idea of the colour.It does look very green in places but I think you are right that weathering will tone it down.I have dull coat to finish it with also.
Thanks for the comments.Will post more pics as I progress.
Cheers.
