KBS Coatings DiamondFinish Clear Satin Aerosol Clear Coat, 15 oz — UV‑Stable, Flexible Durable Finish

KBS Coatings DiamondFinish Clear Satin is a flexible, UV-stable aerosol clear coat that delivers a durable satin finish and covers about 35 sq ft per 15-ounce can.

Built for metalworkers, restorers, fabricators and hobbyists, this aerosol variant of DiamondFinish offers a tough protective topcoat that can be sprayed over painted surfaces or directly onto bare steel. The formula resists yellowing, cracking and peeling while remaining permanently flexible, so it stands up to changing temperatures, vibration and chemical exposure. Each 15-ounce can sprays approximately 35 square feet depending on application technique and number of coats.

How do I use this aerosol clear coat for best results?

Apply to clean, dry surfaces with light, even passes to avoid runs and ensure consistent coverage. Minimal prep is required when spraying over existing paint; however, remove loose rust, contaminants and oil. Multiple thin coats produce a stronger, more uniform film than a single heavy application.

• Shake can vigorously for 2 minutes before use and intermittently during application.
• Hold can 8–12 inches from the surface and spray in sweeping strokes.
• Allow flash time between coats—follow manufacturer drying recommendations for touch and recoat times.
• For bare steel, de-grease and remove loose oxidation before spraying.

Will this hold up outdoors and resist yellowing?

Yes — the DiamondFinish Clear Satin formulation is UV-stable and engineered to resist discoloration over time. That UV stability combined with chemical resistance helps preserve the underlying finish and color on exterior projects.

• 100% UV-stable resin minimizes yellowing from sun exposure.
• High chemical resistance helps against common solvents and fuels.
• Remains flexible to tolerate thermal expansion without cracking.

Can I use it directly on steel or only over paint?

This product is formulated to adhere both over other coatings and direct to steel when proper surface prep is performed. It bonds to painted surfaces with minimal prep and can act as a one-step clear topcoat for many metal restoration projects.

• Suitable over cured paint with light cleaning and scuffing.
• On bare metal, clean and remove loose rust for best adhesion.
• Provides corrosion-resistant protective layer when paired with appropriate primers.

How durable is the satin finish under heavy use?

DiamondFinish Clear Satin cures to a hard, durable film that stays flexible—this combination reduces cracking and peeling under mechanical stress. It’s formulated for demanding environments where vibration, impacts and chemical exposure occur.

• Hard, abrasion-resistant surface for long-lasting protection.
• Flexible film prevents brittle failure on substrates that move or flex.
• Maintains satin appearance without chalking in most outdoor conditions.
