Description

3M Marine Adhesive Sealant 5200 is a tough, flexible polyurethane for permanent bonding and sealing your RV, boat or other watercraft. It is ideal for use on wood, gelcoat, fiberglass, metal and more. It is recommended for interiors, below the waterline and any other places that are shielded from sunlight. It applies right from the container – no mixing is required. It becomes tack-free in 48 hours, and cures to form a firm, flexible, waterproof seal on joints and boat hardware. Far more than a marine caulk, tough, flexible Marine Adhesive 5200 dissipates stress caused by vibration and shock, and won’t crack under dynamic force. It resists saltwater, wind, weather and temperature extremes for long periods of worry-free enjoyment on the water. In fact, for more than 50 years, 3M Marine Adhesive Sealant 5200 has been used and trusted as a marine sealant by professionals in some of the most demanding conditions on earth.

    • I have used this before and like how it seals and adhers
Color: White Size: 10 fl oz Pattern Name: Adhesive Sealant
I started building a wooden boat. I used this product previously on another wooden boat I build. It is fairly easy to work with. It just takes a few day to fully cure and when it cures, it is set for life. I use it in a caulking gun. I have not used the product in the smaller squeeze tube because my project calls for a larger quantity. It is a bit pricey but it is an excellent product for my purpose. ... show more

    • The best you can buy.
Color: Black Size: 10 fl oz Pattern Name: Adhesive Sealant
I use this stuff to apply a rubber base onto wooden instruments. Bonding to rubber is not very easy, but this stuff is great. It is extremely tacky and firm right out of the tube. I keep mine in the fridge to preserve the unused contents, but can also go in the freezer, and is immediately usable even icy cold. CONS: it takes several days to cure hard (for shaping and sanding) but will skin in 1-2 days. Seriously tacky! There is a fast cure variety but it’s only available in white. I need the black stuff. JB wood also has a similar white product. This is seriously on another level. ... show more
