How much reducer? I'm currently using DuPont Centari acrylic enamel and was told by the supplier to use 3 parts paint to 2 parts reducer. The label on the can says 8 parts paint to 2 parts reducer. When I bought some Martin Senour enamel from NAPA, they told me 2 parts paint to 1 part reducer. Do I need a viscosimeter? Is there a rule of thumb about paint/reducer ratios?
