Testing experience has shown that 1.5 mils dry film thickness of Crystal Coat over Zero Rust exhibits gloss and color retention far superior to air dry enamels.  An exceptionally quick dry rates allow multicoat application with as little as 15 minutes between coats.  The finish has excellent flexibility and resistance to surface marring.

Uses:
Specifically designed as color stabilizing gloss surface coating for Zero Rust when a gloss finish is required.  Secondary uses may include resurfacing and brightening of properly de-chalked but otherwise sound aged finishes.  A light sanding or buffing may be required for proper adhesion, providing the surface is lift resistant to Crystal Coat. Other uses may include oxidation protection for non-ferrous metals, i.e., brass, bronze, aluminum, copper and chrome.

Application:
Conventional spray application my be accomplished with siphon, pot, airless, electrostatic or high volume, low pressure equipment.  Thinning with xylene, toluene, aromatic 100 or lacquer thinner @ 10% to 25% may be necessary for some equipment.  Viscosity, as supplied, is adequate for airless and pressure pot sprayers.  Tip sizes in the range of .010 to .014 help reduce over application to protect from runs.

Application over Zero Rust:
Apply Zero Rust as directed.  For optimum protection, a 1.5 mil dry film of Crystal Coat should be applied over Zero Rust.  Apply Crystal Coat when Zero Rust is dry-to-touch-- i.e., when film is dry enough that light pressure with a finger doesn't leave a print.  Dry-to-touch time will vary depending on the Zero Rust film thickness and on curing conditions, but is usually between 30 minutes and four hours.  Apply Crystal Coat as supplied two coats at three to 4 mils wet, or three light coats at two to 3 mils wet when applying thinned materials.  One gallon of Crystal Coat, as supplied, will cover 250 to 275 square  at 1.5 mils dry film.  A 12-ounce aerosol can covers nine to ten square feet at this same thickness.

Note: If Zero Rust is allowed to dry too long after the dry-to-touch stage, wrinkling may result.  If this occurs, Zero Rust needs to cure 6 to 7 days before application of Crystal Coat .  At that time a very light burnishing of the Zero Rust is recommended for maximum adhesion.
