Dicor RV Clear Cap Sealant 351CSCL-1, 10.1 oz — Non‑Sag, Fast‑Drying Weatherproof Sealant

Dicor 351CSCL-1 Clear Cap Sealant is a paintable, non-sag sealant designed to create durable, weather-resistant seams around RV windows, entry doors, compartment doors, and exterior joints.

Keep your RV watertight and factory-finished with a sealant made for mobile home exteriors. This HAPS-Free, clear formula dries quickly, resists UV and water exposure, and adheres to a broad range of substrates including metal, wood, glass, thermoplastics, and fiberglass. It matches Dicor roof systems and works with other Dicor sealants, tapes, and adhesives for integrated repairs or installations.

How does this cap sealant perform during installation?

Application is straightforward: the non-sag consistency allows you to lay a neat bead without runs, and fast tack-up time means less waiting before reinstalling trim or hardware. It’s formulated to be compatible with common RV materials so you can trust it will adhere without special primers in most cases.

• Non-sag formula for tidy horizontal and vertical seams
• Fast drying so follow-up steps are quicker
• Works with Dicor tapes and adhesives for layered sealing

Will the clear sealant match my RV’s appearance?

Clear finish preserves the underlying surface appearance, making it ideal where you don’t want visible color change. Because the product is paintable, you can still color-match if a painted finish is required for trim or repair blending.

• Clear color lets original materials show through
• Paintable once cured for custom color matching
• Available in additional colors (white, black, tan) if solid color is preferred

Which materials and conditions is it compatible with?

Dicor 351CSCL-1 bonds to a wide variety of RV construction materials, from metal frames and glass to fiber-reinforced plastics. It’s designed for exterior use, offering UV and water resistance that suits exposed perimeters and compartment seams.

• Adheres to metal, wood, plywood, particleboard, and rubber
• Compatible with concrete, masonry, glass, thermoplastics, and fiberglass
• Suitable for window and door perimeters, compartment doors, and joints

How long and how much will I need for typical repairs?

The cartridge contains 10.1 ounces, which covers most perimeter seal jobs for a single window or several small trim repairs depending on bead size. Because the sealant is flexible and durable, properly applied beads often extend maintenance intervals compared with temporary fixes.

• 10.1 oz cartridge for single-window or multi-small-joint applications
• Use continuous beads around frames for best water protection
• Combine with Dicor flashing or tape where extra redundancy is needed

Who is this for: RV owners, installers, and maintenance technicians who need a reliable, clear perimeter sealant that blends with existing finishes and bonds to diverse RV materials. It’s suited for those who want a fast-drying, non-sag option that integrates with Dicor systems and supports neat, long-lasting exterior sealing jobs.
