Thanks guys for your comments. Weathering 1/32 models in France is unknown in France and in Europe. We are just a few to try and follow that way of modeling. I will send some more pictures and will explain the different processes in a few days.
The Italians are well skilled and their models are really precise. They use 3D computerized tools as drill.
Usually, most of the modelers just add new tyres, front and rear likages, lights, new paint, extra fenders, front and wheels weights. But no weathering techniques ! Maybe because the young age of modelers ... The oldest collect promotionnal items as Gama, Corgi, Hausser, CIJ, NZG. Due to the high prices, these models can't be use as bases for modeling. Sometimes the cardboard boxes are nicest than the models but the boxes have higher value than the models in.
The main important forum in France is : www.grostracteurspassion.com
This site is about farm subjects and you could find a lot of links (manufacturers, models suppliers, ...). Go and have a look on the FORUM GTP. You may find some good information.
