Key Benefits

• Rapid cure and paint readiness: apply, seal, and topcoat in roughly half an hour under favorable conditions.
• Versatile adhesion: bonds to primed, painted, or bare metal for reliable sealing across substrates.
• All-weather durability: remains flexible and resists shrinking or cracking despite sun, rain, or temperature swings.

• Multi-vehicle compatibility: suitable as a body filler and seam sealer for cars, trucks, RVs, and boats.
• Pro-grade results: trusted by auto repair professionals and designed for consistent, clean finishes.

Recommended Uses and Surfaces

• Seal seams on body panels, roof joints, and other metal joints on cars and trucks.
• Use on RV roofs to create a flexible, paintable seal that tolerates weather changes.
• Ideal for boat hull joints and other metal surfaces exposed to the elements.
• Black color helps blend with common automotive seams for a neat appearance.

How to Use

1. Cut the nozzle and load into a standard urethane caulk gun.
2. Apply a steady bead along the seam you want to seal.
3. Tool and smooth as needed; the material remains workable for a short window.
4. Allow to cure and then topcoat once paint-ready, typically within 30 minutes.

Note: No sanding is required for topcoat readiness in many cases, streamlining repairs while preserving substrate integrity. The included gloves and tip make setup straightforward, and the sealant stays flexible for long-term performance.
