Waterborne paint does not smell as caustic as solvent-based paint, but that does not mean you can spray without protective gear. In fact, just the opposite is true. Despite reduced VOC levels, waterborne paints feature plenty of chemicals that are deadly to humans. A respirator is necessary at all times. In addition, because of slow drying times, the paint lingers in the air longer.
Pros of using Waterbourne paints include:

• Delivers better coverage in fewer coats due to its higher pigment content
• Reduced mil thickness when dry, which reduces paint pulls when bolting down other body components, such as side mirrors.
• Improved metallic lay-down on body surface.
• Reduced gassing out over time-once the basecoat is dry, it is final. Solvents release gas for several months after application, which can affect long-term paint finish.

Cons of using Waterbourne paints include:

• Harder to shoot as it requires a different spray gun and dryers.
• Flash time is critical-it takes longer to dry overall.
• Higher material cost-paints and ancillary products.
• Blending of painted panels is harder, requiring you to learn a new skill set.
• Not a task for home application-a spray booth is required because of slow dry times.
