Hi Mario & Bice,
Hope all is well in the wilds of Italy.
The content & detail of your posts is second to none, but I will have to digest it in stages LOL ! The various alternatives for landscaping / scenery firstly. I can only agree on your summary of the pro's / con's for the traditional & the XPF; & certainly the "mess" / wastage factor on XPF, which I can vouch for currently first hand. Although the hot wire cutter does offer the advantage of sealing the cut surface. However, it does generally look like its snowed indoors !!!!
Your resin / final method is very interesting, & I take it the approach / method you now use. Are there any problems with fumes / flamability / needs for doing the work "outside" or in a very well ventilated space. It appears from some of your pics, certain stages were undertaken "outside". Fine for a modular / demountable layout; maybe more of a problem for a fixed layout. Say as my loft layout, shown in the layouts thread - but no doubt possible.
The advantages in terms of the finished landscapes lightness & strength / impact resistance, must be a real major benefit, for exhibition / demountable layouts; over the vunerable final product with traditional & XPF methods.
Thanks again for the detail, & excellent food for thought. You mention in the text re - others using the various different methods, are they also Italian railway modellers; is it a popular hobby over there, out of interest ?
Next I will attempt to understand the technical side of your wonderful model - it could take a "while" LOL !!!!!!
Cheers,
Norm
