U-POL Black Tiger Seal automotive adhesive-sealant 310ml cartridge — waterproof, paintable, gap-filling

U-POL Black Tiger Seal is a waterproof, paintable adhesive-sealant in a 310ml cartridge made to permanently bond and seal vehicle panels, trim, windows and lights.

When you need a durable seam seal that sticks to body panels, fills gaps and stays watertight, this cartridge-form sealant offers a straightforward solution for collision repair, restoration and routine maintenance. Supplied in a standard 310ml cartridge, it dispenses smoothly for bead application and cures to a resilient black finish that accepts most paint systems. Its gap-filling properties and compatibility with anti-flutter foam replacement make it useful across multiple vehicle sealing tasks.

How does this sealant perform on car body panels and trim?

Black Tiger Seal is formulated to provide a permanent bond that resists moisture and holds trim in place. It adheres to common automotive substrates and cures to form a tough, flexible joint that reduces the risk of panel movement and water ingress.

• Forms a permanent bond between metal and plastic trim components.
• Maintains flexibility after cure to accommodate vibration and thermal expansion.
• Completely waterproof once fully cured, preventing leaks around seams.

Can I use it around windows, doors and lights, and will it accept paint?

Yes — the product is suitable for sealing around windows, doors and lights. After curing, most paint systems can be applied over the sealant, allowing for a finished appearance without removing the bead.

• Compatible with many automotive paint systems after full cure.
• Creates a neat, paintable surface for final refinishing steps.
• Works for sealing light housings and door perimeters to block moisture.

What gap sizes and repair tasks is it best suited for?

Black Tiger Seal has good gap-filling capability, making it effective for medium-width seams, joints and voids. It’s also suitable where replacement anti-flutter foam would normally be used, helping to restore panel stability and reduce noise.

• Fills and bonds medium gaps between panels and trim pieces.
• Useful for replacing anti-flutter foam in cavity or seam repairs.
• Dispensed from a 310ml cartridge for controlled bead sizes on-site.

How do I apply and finish the sealant for best results?

Dispense with a standard caulking gun and lay a consistent bead; tooling the bead after application improves adhesion and appearance. Allow the recommended cure time before painting or subjecting the area to water exposure to ensure full performance.

• Use a caulking gun compatible with 310ml cartridges for even application.
• Tool the bead smooth with a spatula or scraper within the working time.
• Observe manufacturer cure times before painting or exposing to moisture.

Who is this for: technicians, bodyshops and DIY restorers who need a reliable, paintable automotive sealant for perimeter sealing, trim bonding and gap filling. It’s suited to users seeking a waterproof, flexible adhesive that dispenses from a standard 310ml cartridge and integrates into paint and refinishing workflows.
