Hikarux, these are good paints, not as good as Gunze acrylics IMHO, but still very good.
You can thin them with Tamiya acrylic thinners, just thin them 50/50 and they will spray very well indeed.
They cover all the main colours, ie Luftwaffe, USAAF, RAF etc, as well as some of the less obvious, such as WWII Italian colours.
Well worth trying.
