1 Shot 6002 High-Temp Reducer thins 1 Shot lettering and bulletin enamel for hand lettering, striping, and spray work in warm conditions above about 75 F, slowing the film so it levels before it sets. It extends open time and improves flow for clean strokes without dulling gloss or weakening adhesion. Add roughly 5 to 10 percent for brush and up to 20 to 25 percent for spray. Supplied in Quart.
