KBS Coatings DiamondFinish Watercolor Clear Coat 1 Quart (32 oz) — Single‑Part, Non‑Yellowing Gloss, UV & Scratch Resistant

KBS Coatings 8404 DiamondFinish Watercolor Clear Coat is a single-component, non-yellowing protective topcoat that delivers diamond-like scratch and weather resistance for indoor and outdoor projects.

DiamondFinish is formulated to give a crystal-clear, durable film without mixing hardeners, making it convenient for hobbyists, craftsmen, marine applications, and general repair work. It bonds to many substrates — including metal, wood, plastic, fiberglass, and existing painted surfaces — and resists UV, moisture, saltwater, and abrasion so finishes stay bright and clear longer.

How does this clear coat protect surfaces?

DiamondFinish forms a tough, glossy barrier that absorbs impact and resists scratches better than standard clears. Its weather-resistant chemistry prevents fogging, clouding, and yellowing even under prolonged sun or marine exposure.

• High scratch and impact resistance for long-lasting appearance
• Durable against salt spray, humidity, and UV exposure
• Maintains optical clarity — keeps whites and natural grains true
• Seals against moisture and environmental contaminants

Do I need a hardener or special measuring to use it?

No hardener is required; this is a single-part (one-step) clear coat you stir and apply. That simplifies application and eliminates pot-life or mixing-ratio concerns common with catalyzed systems.

• Ready-to-use straight from the can after light stirring
• No cross-mixing, fewer tools, and reduced setup time
• Smoother workflow for small projects and quick touch-ups
• Compatible with brush, spray gun, or dip applications when thinned per instructions

What surfaces and projects are suitable for DiamondFinish?

It adheres well to a broad range of materials, making it a versatile topcoat for both hobby and industrial uses. Minimal surface prep is often sufficient, but follow standard cleaning and sanding practices for best adhesion.

• Ideal for fishing lures, automotive trim, boats, and outdoor furniture
• Works on metal, wood, plastic, fiberglass, and existing paint
• Great for decorative projects where clarity and non-yellowing are essential
• Useful in marine environments because it resists saltwater and humidity

How do I get a durable, glossy finish with this product?

Proper surface preparation and application technique are key: clean, degrease, and scuff the surface, then apply even coats, allowing recommended flash times between passes. Multiple thin coats build a harder, clearer film than a single heavy coat.

• Remove oils, dust, and contaminants before coating
• Sand lightly or scuff glossy surfaces for better bonding
• Apply several thin, even layers with proper drying time
• Can be sanded and buffed after cure for mirror-like shine

Who is this for: KBS Coatings DiamondFinish is designed for makers, restorers, marine owners, and professionals who need a high-clarity, weatherproof topcoat without the complexity of two-part systems. If you want a single-product solution that protects and preserves color and grain while resisting UV, salt, and abrasion, this clear coat is built to meet those needs.
