Another thing I like to use are waterslide decals for those really small details. I haven't had much success with the white sheets, but the clear ones are great! The white ones are for placing over dark colors or for making white designs, lines etc. but for clones, the clear ones are all you need.
Spud uses Citadal paints I think so he'd be the one to ask about them. I actually use Americana acrylics. They're cheap and come in tons of colors. They're not top of the line, but I like them. They make varnish to seal everything too. I just use water to thin them. I don't use actual thinner. I've never had any problems.
