Hi Nick
Thanks for the reply. Would sure like to see that technique in action. I watched a good Youtube video on creating graffiti. It involved making masks of the graffiti in various layers so that the different colours and different parts of the design shapes fitted together properly. It looked amazing and I would like to try that. But I expect that in the period I would mode,l the only graffiti would have been 'wot no ......?' and none of the amazing graffiti you can see these days.
Your weathering is definitely an inspiration. I was lost a bit with the wagon types though. But the production line for the rakes was interesting to see.
Cheers
