*NOTE: Certain coatings have inherently poor adhesion, especially if manufactured without effective substrate preparation, particularly gold and silver coatings and replicated aluminum gratings. That being said, we and our customers have successfully protected and cleaned lots of gold and silver mirrors and gratings including those on the WM Keck Telescope and the Gemini North Silver. The Laser Gravitational Wave Observatory (LIGO) uses our red polymer formula exclusively to clean their gold optics as documented here. While we routinely clean diffraction gratings, the old adage about gratings still holds - don’t touch them unless you have to! And remember: Always test on an inconspicuous or non-critical area first.

Red First Contact Spray formula is now supplied premixed and has been improved for ease of application while maintaining or improving other performance attributes. The results are a better spray pattern from our sprayers, resulting in simpler application to vertical surfaces and a stronger film to resist tearing. The polymer retains it's outstanding ability to clean to the molecular level while improving usability.
