Buying Guide

Key purchase considerations include: surface compatibility, UV protection, and anti-static or anti-fog properties. For marine environments, UV resistance helps prevent yellowing and cracking, while anti-static finishes reduce dust adherence on open-water days. Consider whether you need a spray-on protectant, a cleaner with restorative polish, or a treatment designed specifically for Strataglass or Eisenglass. Evaluate ease of use, drying time, and whether the product leaves a matte or glossy finish. Compare products on how well they maintain clarity after exposure to salt spray, sun, and temperature fluctuations. Lastly, verify compatibility with your boat’s plastics and vinyl types to avoid haze or residue.

Additional considerations:

  • Surface type compatibility (vinyl, acrylic, polycarbonate, etc.)
  • Frequency of application for optimal UV protection
  • Residue and scent preferences (low odor, non-greasy finish)
  • Ease of removal of residues or streaks
  • Impact on anti-fog or anti-static properties
