**UPDATE** Added 2nd video with a little more "how-to"
I spend a lot of time in hobby shops. I have walked past the rack of "Plastruct" stuff many-a-time but until now, have never played with it. Typically, it is used by model train guys and many of the pieces they sell are to scale (i.e. HO scale). I never knew just how great this stuff was...
The package says that it is either white styrene or grey ABS (even clear) and is ideal for vacuum forming and scratch model building. I have not vacuum formed yet, but I have built a few models from scratch and so far, I ADORE this stuff.
The concept is pretty simple, score and snap to cut to size, and “weld” together via a solvent-based “glue”. Both curved and straight cuts seem to snap equally well and after dry, the joints seem to be of one piece --just like a real weld. The finished product is light as a feather and with some careful construction (I.e. gussets in the corners) is quite strong. I can’t say enough for this stuff, it is a real dream to work with.
