Ah, I didn't know about the hockey guy. XD No wonder some of those are unfamiliar because I only own 2 of those 5 sets. I missed out on getting any Biomecha, as well as any from the 2 races added for series 2. T.=.T Otherwise, I'd have done something similar to this. XD
Really, it's the brush and the paint. Sure, it takes a little knowhow, but when it comes to a really simple coat like this, you just need the right equipment, not the right skill. You should definitely give it a shot.
