I have started on an old Tamiya 1/25 Tiger I I picked up for a song ($10 USD!). It's fairly well-detailed for a kit of 1969 vintage, even if it's a fit-up nightmare (that's another thread). It has the snap-together track links, which I cannot replace with AM treads, for budgetary reasons, not to mention that I've heard that the kit-supplied sprockets won't fit the more accurate AM treads, anyhow. Thing is, the OOB treads are of some "soft plastic," the composition of which I do not know. Does anyone know what sort of plastic this is?
Some discreet experimentation has confirmed that none of the usual solvents/glues for polysty have any effect on this stuff. I'd like to do some filling and putty-ing, and don't have anything that will work. Nuthin sticks to this stuff; makes me wonder if it's some form of teflon or nylon or HDPE, or something.
Anybody got any idea what sort of plastic Tamiya was using circa 1969?
