Ronan R-722 Low-Temp Reducer thins Ronan One Stroke lettering enamel for hand lettering, striping, and spray work in cooler conditions below about 75 F, where it helps the film set up at a normal rate. It extends open time and reduces brush drag for clean strokes without sacrificing gloss or adhesion. Add roughly 5 to 10 percent for brush and up to 20 to 25 percent for spray. Supplied in Pint.
