Add to CartPettit 121 Spraying Thinner is a general purpose thinner for thinning spray enamels for easier application. Many paints when stored for some time before use will increase in viscosity and should be thinned with a good thinner for normal spray application. The thinner flashes out rapidly and allows an applicator to apply a light tack coat followed by a double spray coat.
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.
**Can Be Shipped Ground Only in the 48 Contiguous States.**
