3M Urethane Seam Sealer, 08367, Black Color, 310 mL/10.5 fl oz Cartridge

Customers find the seam sealer performs well, filling seams and gaps effectively, and appreciate its ease of application with a normal caulk gun. The product dries quickly, stays flexible, and provides a sturdy hold, with one customer noting it holds up well against vibration and moisture. The applicator tip is missing from the package, and while some customers consider it excellent value, others find it pricey.
