Oh yes, I hate sanding for some odd reason. Well, actually I like it, but only for some seconds. Then it gets too tedious and dirty. They should really invent something, which makes sanding obsolete. I think it'd be the most bought scale modeling invention.
Regarding your Subaru: Still looks great. I am looking forward to the decals and stuff. Oh and btw, there was some japanese guy actually building a Subaru WRC thingie. Maybe you can get some help or tips out of the videos!
