FlatOut QuickStrike Tyre Sealant for RVs & Trailers — 32 fl oz Kevlar‑Reinforced Fast‑Flow Formula

FlatOut QuickStrike Tire Sealant is a fast-flowing, Kevlar-reinforced liquid that seals punctures and stops slow leaks in RVs, trailers, and small tires with a one-time application.

FlatOut QuickStrike On Road Formula is designed to suit larger, non-passenger applications such as RVs, boat and horse trailers, and utility trailers. The formula moves quickly to a puncture, forms a durable seal, and remains water-washable and latex-free so it won’t gum up rims or dry into flaky residue. It works in both tubed and tubeless setups and is optimized to seal tread-area punctures up to ½ inch.

How quickly will QuickStrike seal a puncture?

QuickStrike was formulated to reach punctures faster than traditional sealants so it can act immediately when air escapes. The product’s flow properties allow it to close holes rapidly, minimizing air loss and giving you more time to safely reach service or continue your trip.

• Flows rapidly to the puncture for immediate sealing action
• Designed for fast deployment where rapid air loss occurs
• Helps avoid immediate flats during transit

What makes Kevlar-containing QuickStrike different from other sealants?

FlatOut QuickStrike includes super-strong Kevlar fibers that form a reinforcing matrix at the puncture site. Unlike particle-only sealants, the Kevlar fibers add tensile strength to the patch, improving durability while remaining clean and water-washable.

• Kevlar fibers reinforce the seal for long-lasting protection
• No latex or adhesive binders—less mess and no flaky residue
• Water-washable formula makes rim cleanup straightforward

Which tire types and puncture sizes can QuickStrike handle?

QuickStrike is suitable for tubed and tubeless tires on trailers, RVs, and similar vehicles—not recommended for standard passenger cars. It’s engineered to seal tread-area punctures up to ½ inch and to significantly reduce slow leaks that would otherwise require frequent topping up.

• Effective on tubed and tubeless tires used on trailers and RVs
• Seals tread punctures up to ½" (12.7 mm)
• Reduces or eliminates slow leaks for extended on-vehicle protection

How long does protection last and is maintenance needed?

FlatOut QuickStrike is promoted as a one-time application that provides ongoing protection for the life of the tire when used as directed. Because the formula is non-drying and non-flammable, it won’t form hard clumps inside the tire, and there’s no adhesive residue to remove during routine maintenance.

• Designed as a single application for continuous protection
• Non-drying, non-flammable, and non-corrosive formulation
• Easy to clean up due to water-washable properties

Who is this product for? FlatOut QuickStrike On Road Formula targets owners and operators of RVs, trailers (boat, horse, utility), and similar vehicles where rapid puncture sealing and low-maintenance protection matter. It’s ideal for fleet managers, full-time travelers, and anyone who wants dependable on-road puncture defense without sticky latex residue. Not recommended for regular passenger cars—select a passenger-vehicle formula if you need a sealant for that use.
