It cures to form a firm, rubbery, waterproof seal on joints and boat hardware, above and below the waterline. 3M Marine Adhesive Sealant 5200 offers permanent adhesion to wood, gelcoat and fiberglass. In addition, our marine adhesive sealant is flexible and allows for structural movement and dissipation of stress that may be caused by vibration, swelling, shrinking or shock.

Review: Great sealant - used to reseal around my pool skimmer and also some leaking waders - Good permanent sealant - takes a day or so to harden but great stuff
Review: Amazing product. - This product was recommended to me for use as a glue for brackets on the roof of a van that would hold a solar panel. This stuff is GREAT! A little messy to use but dries to the touch within a few hours and was completely cured within the timeframe stated on the label. It has not degraded at all on the roof of the RV which is constantly in harsh sun and rain and NOT garaged. I would not hesitate at all to use this as a glue for almost any application where a secure bond is required. You will definitely need to allow it the proper time to cure prior to use. It's costly but well worth the expense.

### ⭐ Missing Applicator
*by D***R on April 6, 2025*

Great product if I had an applicator. As other reviewers have noted, received sealant without applicator nozzle so I am unable to use. I figured maybe seller would have corrected this problem but I figured wrong. Tube is in good shape though. MFG date 01/29/24. "Free" returns means a 70 mi round trip to nearest UPS store.
