there is already a long running gundam and mecha modelling thread here: https://forum.lowyat.net/topic/4140579 . no need for a new one.

in Malaysia, buying from hobby stores will get you better prices than buying TRU, Aeon and the likes. don't really need to go to Japan to enjoy the hobby.

most of the newer MGs don't really require much work. a basic top coat should suffice.
