ill say it again, the best thing i ever did was get rid of diamont and go with wanda. 1/3 the cost and i actually like it better. it way better for masking, 2 tones, graphics, all that kind of stuff. covers as well or better. the little bit of color matching i do has always been right on the money. i have zero complaints with it. i dont use their primers or clears though. i use spi reducer in the base and all spi primers and clears. i have been told the wanda reducer is super fast so the spi really works great with it. from an inside source i have been told that wanda is the old sikkens autobase which was their premium line before autobase plus. this is why all the sikkens color tools and formulas work with it. if thats true or not i dont know but the source is pretty reliable.
