Gradius II Die-cast Vic Viper

[Valkyrie]

Yeah, "poly" kits were basically made of Bondo. They were sorta popular in the 80s GK scene but mostly I associate poly kits with really really bad bootlegs. I think that stuff went away when the bootleggers ended up surpassing the quality level of the original creators.

No, bondo is polyester.  This is made of polyurethane resin (ポリウレタン, on the second line of text on the box,  means polyurethane).  It's the good stuff.
I've seen a lot of crap bootleg kits made of polyester resin, but never original garage kits from Japan.
So if one of you wants to buy this, you'd probably be paying too much, but you'd be getting a good quality kit.

You guys can punch me, especially because I loved drawing (and looking at) very technical illustrations of weapons/vehicles (when I was a kid)....but these days?

 I WANT SUPER-DEFORMED versions of Vic Viper...I want Parodius kits, really.

Truth.

Oh well, thanks for making clear what that kit is made of. I'm only used to paint on polystyrene, polycarbonate and some gk resin (but please don't ask me what exact kind of resin, I have no idea).
There seem to be a lot more materials like polystone, polyvinylchloride, etc. I used polyurethane only as a foam for insulating purposes (and my better half uses it for her cosplay weapons).
