What kind of sprayer do you recommend with System Three WR-LPU?

Below is the section on spray application from our latest detailed paint literature:

Conventional cup guns and HVLP paint sprayers are not recommended for spraying WR-LPU.  Best results are achieved using pressure pot or airless spray setups.

Pressure Pot Spray:

Purge lines with denatured alcohol and follow with fresh water. Reduce WR-LPU as necessary up to 25% by volume with water.
When spraying WR-LPU, the first coat should be applied ultra-thin, avoiding dry spray. This coat should look patchy over the substrate. After a minimum of 15 minutes, apply a medium wet coat at 3-4 mils.
Wait a minimum of 2 hours before applying the next coat.
No sanding is required within 24 hours. After 24 hours, sand with 220-320 grit paper. Remove sanding dust by flushing the surface with plenty of clean water. Dry with a lint-free towel. Apply additional coats in the same manner.

Suggestions for spraying:
• Pot pressure: 10-15 psi
• Atomization pressure: 30-50 psi
• Tip size: 1.0-1.2 mm
• Reduction: As needed up to 25% with water
Tips for success:
• After spraying a coat, submerge the tip of the gun in water. This prevents the polyurethane from setting up in the tip and cap. Before use, wipe excess water from the end of the gun. Point the gun in a safe direction and pull the trigger a few times to displace any water.

Airless Spray:

Purge fluid lines with denatured alcohol and follow with fresh water. No thinning of the WR-LPU is necessary with airless spray. If environmental conditions require, thin as necessary up to 5%.
Hold the gun 16” from the surface and move quickly, applying an ultra-thin first coat. The surface should be patchy over the substrate. After 15 minutes, apply a medium wet coat at 3-4 mils. Wait a minimum of 2 hours before applying the next coat.
No sanding is required within 24 hours. After 24 hours, sand with 220-320 grit paper. Remove sanding dust by flushing the surface with plenty of fresh water. Dry with lint-free towel. Apply additional coats in the same manner.

Suggestion for spraying:
• Pressure: 2700-3000 psi
• Hose: ¼” ID
• Tip size: .009-.011
• Reduction: As needed up to 5% with water
Tips for success:
• After spraying a coat, submerge the tip of the gun in water. This prevents the polyurethane from setting up in the tip and cap. Before use, wipe excess water from the end of the gun. Point the gun in a safe direction and pull the trigger a few times to displace any water.
