Dicor 351CSCL-1 HAPS-Free Cap Sealant – Clear for RV Windows & Doors

Overview

The Dicor 351CSCL-1 HAPS-Free Cap Sealant – Clear is designed for RV maintenance, delivering tight, weather-ready seals around windows, entry doors, compartments, and joints. This non-sag formula stays in place as you work along vertical seams and uneven edges, then dries to a flexible finish that helps keep out drafts and moisture. While Clear is the focal finish, this sealant family also offers White, Black, and Tan options, giving you flexibility to match or accent your RV exterior. A 10.1-ounce tube provides a practical balance of coverage and control for projects big and small.

Real-world use cases

Use the Dicor cap sealant to seal around RV windows to help minimize drafts, around entry and compartment doors for reliable closures, and along joints where panels meet.

Whether you’re sealing a fresh install or refreshing aging seals, the product supports practical, long-lasting results without promising guaranteed performance.

Practical application tips

• Prepare surfaces by cleaning and drying thoroughly before applying.
• Apply a steady bead to perimeters of windows, doors, compartments, and joints.
• Allow the sealant to dry and, if desired, paint to match or accent finishes.

Whether you’re maintaining an old favorite or prepping a new build, the Dicor 351CSCL-1 sealant offers a paintable, weather-resistant option that supports a neat, durable finish for RV exteriors and interiors.
