3M 4000 UV Marine Fast Cure Sealant

3M 4000 UV is a fast cure medium strength sealant used to bond and seal metal, gelcoat, fiberglass, wood, and plastic. A one-part polyether adhesive sealant with excellent UV resistance, 4000 cures to a firm, rubbery, watertight seal. This sealant is ideal for bonding deck hardware, hatches, portholes, railings, and navigation lights.

Suitable for use both above and below the waterline, 4000 Fast Cure is sometimes more appropriate than 3M 5200 polyurethane for parts that may never need removal or replacement. Available in White or Black in various sizes.

      Comments about 3M 4000 UV Marine Fast Cure Sealant:

      I used this product on a boat project, I took an old boat 79, and rebuilt it, this product was very usefull in filling the multitude of holes that various owners had put in the boat, it worked very well for use with fasteners of different kinds,to seal them from leaking it covered well with paint. It is a bit messy to use and caution should be used when using it, to keep from getting it in places you do not want it. It cures quckly, and can be sanded to some extent, not recomended for a dent filler or anything like that.

        An excellent, easy to use product. Jamestown should use the correct illustration for the 3 oz. tube.
        A 10 oz. cartridge is shown. Otherwise, an excellent product.

          Tried both 4200 and 4000 for deck hardware/trim. 4000 stays white and is easier to clean up.
