## Description

3M Marine Adhesive Sealant Fast Cure 4200FC bonds and seals fiberglass, gelcoat and wood. Ideal for rub-rails, stern-joints, deck and through-hull fittings, and access plates. Medium strength allows for disassembly. Bonds and seals fiberglass, gelcoat and wood. The ATG tape system delivers a controlled application of the adhesive while the liner rewinds into the ATG applicator. It bonds on contact, and works on a variety of substrate or material combinations. Warning: This product can expose you to chemicals which is [are] known to the State of California to cause cancer and birth defects or other reproductive harm.

Review: 3M 4200 sealant is great for marine applications. I recently had a swim step screw which pulled out of the transom, so after plugging the hole with epoxy and drilling it out, I used this product to provide a water tight attachment point for the swim step frame, and to provide additional adhesive strength for the repair. The sealant is easy to use, but plan to wear gloves during application as it can get messy. Also note that this product does not adhere to rubber very well, as I tried to use it to attach new rubber soles to a pair of shoes but it did not work for this purpose.
Review: Works as advertised!
