Well, that is the Mother of all Barracuda net 101s. Unfortunately it only covers the net and not the mats. Canmedic is right: you need to ruffle the surface - best before the glue sets. Otherwise it looks too flat. I too agree with Dragon164 that regular tin foil seems to be too thin (mostly 12 - 16 µm). For scale 1:72 I use 30 µm thick aluminum foil as base mat. So for scale 1:35 duct tape - which I think should be around 50 µm thick - seems to be a better option. Plasticwarfares technique gives excellent results in scale 1:35, in 1:72 it did not work for me. Here ist the method I figured out:
I think with a few tweaks you should be getting where you want to. Thumbs up.
