Dicor RV Clear Cap Sealant 10.1 oz — HAPS-Free, Non-Sag, Paintable RV Perimeter Sealant

Dicor 351CSCL-1 HAPS-Free Clear Cap Sealant is a clear, non-sag perimeter sealant formulated to create durable, paintable seals around RV windows, doors, compartments and panel joints.

When you're maintaining an RV, the seams where windows, entry doors and storage hatches meet the body are prime spots for leaks and wind noise. The Dicor cap sealant offers a fast-drying, weather-resistant way to seal those edges while remaining compatible with many common RV substrates. Its clear finish preserves the look of your exterior trim and is paintable when a color match is desired.

How does this sealant perform on RV seams and perimeters?

The formula resists sagging on vertical or overhead joints and cures into a flexible, watertight bead that accommodates movement. It is designed for exterior exposure, standing up to sunlight and rain without running or losing adhesion.

• Non-sag consistency for clean beads on vertical surfaces
• Fast tack and curing speed for quicker return-to-service
• UV-resistant to reduce yellowing and degradation outdoors
• Remains flexible to handle thermal expansion and vibration

Which materials and products is it compatible with?

Use it across the common materials found on RVs and trailers; it bonds to metals, fiberglass, glass and most plastics and wood substrates. It also works alongside other Dicor sealants, tapes and adhesives, making it easy to integrate into existing repair routines.

• Bonds to metal, fiberglass, glass and thermoplastics
• Adheres to wood, particleboard and plywood edges
• Compatible with concrete, masonry and reinforced plastics for broader repair needs
• Designed to pair with Dicor accessory products for system compatibility

What are the application and finish options?

Applied from a standard 10.1 oz cartridge, the sealant lays down a smooth, clear bead that blends with surrounding surfaces. It sands and accepts paint after curing, so you can match body colors or trim if a seamless look is preferred.

• 10.1 oz cartridge fits common caulking guns
• Clear finish preserves underlying materials' appearance
• Paintable after cure for color-matched repairs
• Easy tooling and cleanup while fresh for neat lines

How do I use it for long-lasting results?

Prep the joint by removing old sealant, dirt and oils, then apply a continuous bead and tool it to form full contact with both surfaces. Allow the sealant to skin and cure per conditions; warm, dry environments speed curing while cold or damp conditions lengthen it.

• Clean and dry surfaces before application for best adhesion
• Apply steady bead with a caulking gun and tool for uniform coverage
• Observe recommended cure time—temperature and humidity affect speed
• Use with Dicor primers or tapes when specified for problem substrates
