I own Gray fox aswell and says tokugawa, the materials are hard plastic like Solid Snake , except the crotch piece because is softer platic or rubber ¿? (not sure )
The helmet is light greyish (and has metalic finish somehow) but is'nt glossy at all (however not matt finish)
All the joints are very tight, but did'nt have any problems with poping out parts or painting as you say (the elbow joints are'nt painted, its just the base and natural color of the plastic )
Can't tell you if yours is bootleg or not, but Just one advise: Do'nt trust on Taiwan sellers man..I tell you from my own experience
Anyways
Lonewolf posted this info about bootleg Gray Fox:
Sharing a Bootleg alert for the Play Arts Kai Cyborg Ninja, source is PTK (PinoyToyKolektors) forum:
TCKUGAWA instead of TOKUGAWA
- little to no gloss finish on the mask
- white finish

Box has a serial number, but the Font/lettering is different compared to other PA Kai boxes (Sneaking Suit Naked Snake, Batman), which are all the same font
