3M Marine Adhesive Sealant 4000 UV is a professional-grade, medium-strength polyurethane sealant designed specifically for marine applications. This fast-curing formula creates a durable, flexible bond that withstands constant exposure to sun, saltwater, and harsh marine environments while still allowing for future disassembly when needed.
Key Features:
Ideal for sealing hatches, ports, windows, deck hardware, and through-hull fittings. The medium-strength formulation provides a secure seal that can be removed for maintenance or repairs without damaging substrates. Black color provides a professional appearance and hides well against dark surfaces.

Would like to use PayPal to pay for item, couldn't figure out how to do so. Also, received the item in a very timely manner, however it was the wrong item.
