MIXING INSTRUCTIONS
Use only top quality paint. Inferior paint voids SMITHCO warranty.
1. Completely follow mixing instructions on paint container.
2. Never use mixed paint without straining.
3. The depth of the color of the line will be determined by percentage of water added to the
paint. In most cases, the mix should be at least 2 parts water to 1 part paint. NEVER use
more than 50% paint.
4. Use spraying nozzle TeeJet 8002VS tip only. These tips have been tested and work best
with the SMITHCO pumping system.
