121 Spray Thinner is a fast evaporating thinner
used to reduce most Pettit, Z*Spar and Shipendec products before spray
application. This thinner flashes out rapidly.
Recommended Use: Thin the paint about 10% to 20% and mix thoroughly. For better calculation of the proper spray viscosity, the reduced paint can be checked with a viscosity cup. Enamels should be thinned to about 20 to 25 seconds viscosity in a #2 Zahn cup.
