Review: Perfect for urethane-based paints. - I like to build scale model cars. I have never used urethane-based paint before, but I found a color online that I really liked and realized I didn't have any reducer/thinner for thinning the paint or to do clean up. I got this product and it worked perfectly. I see more urethane-painted models in my future so this will become a regular part of my workshop. AAA+++
Review: is it really worth it? - Great reducer for spraying paint, but honestly I couldn't tell the true difference in this as a reducer to Lacquer thinner. The only thing I can think is that this says that its specific for this but when I ran out as its only a quart vs a gallon, to the thinner I went and can't tell when and where it changed.
