Devcon Silicone Adhesive is a clear silicone that can be used for sealing, caulking and bonding a variety of materials. Great for weather-proofing electrical components, sealing or repairing windows, door frames, vinyl tops and more, this adhesive forms a tough, flexible and waterproof seal that resists aging and weathering without hardening. Bonds: metal, glass, rubber, plastic, silicone resin, wood, ceramic, and painted surfaces. It is good to use removable tape on any area that you do not want silicone to get on, simply remove the tape before the adhesive cures. Non-Flammable.
