  • Duratec Hi-Gloss Topcoat is designed to be applied when the ambient temperature and part temperature are both above 68°F.
  • Catalyze with 1.75-2.25% MEKP Catalyst. A low Hydrogen Peroxide (monomer) catalyst is recommended to avoid off-gassing and porosity. Mix completely.
  • Hi-Gloss Topcoat shold be applied by spraying. Spray with an HVLP Spray Gun, or with a gelcoat application system. Seek a fine spray, and use the lowest pressure that allows an even spray fan. (approximately 40 psi). A 1.8 mm tip is recommended.
  • The first coat should be a light dust coat. The dust coating does not completely cover the surface. Wait at least two minutes, and apply another light coat. After two additional minutes, begin build coats of 4-5 mils per pass, waiting 2 minutes or more between passes.
  • Apply at least 18 mils for even and complete cure. . Recoat before the Topcoat has set up and lost its tack. If the Topcoat cures completely wait at least eight hours, sand, and recoat.
  • Additional solvent is not needed for most spray guns. If solvent is required, do not add Acetone or Styrene. Duratec Thinner is the best choice. High quality urethane reducers are good choices. Lacquer Thinners are not recommended.
  • Sand when the primer has cured. Start with the finest paper that will remove the surface profile. If sprayed well, 220 or 320 grit paper is a good starting point.
  • Wait at least eight hours from the start of sanding before polishing or topcoating.
  • Aqua Buff 1000 and Aqua Buff 2000 are good choices for compounding and polishing Hi-Gloss Topcoat. Use Aqua Buff GlossMaster and a foam pad for final finishing.
