Buying Guide: Key Purchase Considerations

  • Mix Ratio and Application: Most kits use a 4:1 mix with a 2.8 VOC packaged option. Confirm your spray equipment compatibility and reducer needs before buying.
  • Finish Type: Choose between gloss and satin/regular black finishes based on your project goals and vehicle style. This selection affects color perception and maintenance requirements.
  • Color Range and Metallics: If you need metallic or deep black tones, consider kits specifically labeled for metallic finishes or those that deliver uniform color without mottling.
  • VOC Compliance: If you work in a shop with strict VOC limits, verify packaging VOC levels and local regulations. The 2.8 VOC packaging is common for these AU-based systems.
  • Included Accessories: Strainers, hardeners, and mixing sticks streamline workflows. Kits that include these items help ensure consistent results and reduce additional purchases.
  • Project Scope: Gallon kits suit larger panels and fleets, while quart kits are ideal for smaller jobs or color matching work. Consider future projects to maximize value.
  • Durability and UV Stability: Two-component 2K urethanes typically offer superior exterior durability and UV resistance, essential for outdoor vehicles and show pieces.
  • Environmental and Safety Considerations: Use in well-ventilated spaces with appropriate PPE and follow all local regulations for application and curing times.
