•Throughly clean and dry surface from oil, dirt and grease. Allow to dry completely before applying silicone. 
•Cut the seal at the top of the cartridge and cut the nozzle at a 45° angle, to the size of the gap opening. Screw the nozzle to the top of the cartridge.
•Place the cartridge into a caulking gun 
•Hold the caulking gun at a 45° angle. Press the nozzle opening against the joint, apply steady pressure to the caulking gun and extrude the silicone sealant forcing the sealant into the gap and move in a pushing motion, along the joint in one smooth action.
•For a smooth finish, smooth with a finger dipped in mineral turpentine.
•Excess sealant must be cleaned up before the sealant skins in 5-10 minutes.
•Remove tape before the sealant skins. Clean tools immediately in mineral turpetine.
•Avoid smearing on surrounding surfaces
•Sealant will cure fully in 48 hours. As this point any unwanted sealant can be removed by trimming with a sharp blade, but avoid under cutting the seal.
