Glad you like it man!
Actually, I used both Tamyia Acrylics and Testors Enamels. I was very hesitant about the enamels, but after a bit of testing it looked like no degradation of the suit was forthcoming so I said screw it!
Besides, the paint peels off anyway, so who cares really if these paint apps peel off... as long as the suit itself goes undamaged!
If you go a couple of posts back you can see the first round of repaint, without the balck wash.
To achieve a look like the HT figure you'd probably have to repaint the whole figure black and then start adding layers of lighter colors to achieve contrast. I wasn't really willing to do that, because a) the paint would undoubtedly peel off and b) I wanted to find a different "look" and not the usual "dark with light dry-brushing + tiger stripes camo" effect.
