Product Description
SEM 39777 High-Build Self-Leveling Seam Sealer is a two-component, self-leveling seam sealer that produces a smooth, OEM-quality bead on horizontal seams in collision repair. Ideal for trunk floors, floor pans, and other flat surfaces where a traditional gun-applied seam sealer would sag or leave tool marks.
Key Features:
- Self-Leveling: Flows out to a smooth, factory-appearance bead on horizontal surfaces.
- High Build: Fills gaps and seams in a single pass.
- Dual-Mix Cartridge: Two-component formula with static mix tip for consistent results.
- Paintable: Topcoat with automotive refinish systems after curing.
- OEM Appearance: Smooth finish duplicates factory floor pan and trunk seam seal profiles.
