Hi Everyone, Ken sent me a few samples of the spectra-tex a while ago - hadn't heard anything about it and thought meh... I've only just opened the samples and started spraying out of the bottle and i'm blown away by the performance. Now i'm not too sure about specs like if they can be used on hard surfaces etc - but for my use (i.e. water based private artworks) they are kicking butt! running them through a renegade krome they are one of the smoothest, finest paints i've used - however i changed the tip setup in my iwata to a 0.2mm and the detail i can get is phenomenal. tip dry is still an issue of course as it's a water based, pigment paint.. but i guess you just have to live with it. Just thought i'd let anyone know who's interested that i really do back spectra-tex paints. I'm genuinely impressed at their performance... highly recommended.
