Clean the damaged area completely using acetone or rubbing alcohol.
Use sandpaper to rough-up the surface of the tank.
Cut a piece of fiberglass cloth that is slightly larger than the damaged area.
Put on gloves. Using the Syon Seal-N-Place kit, break off the tip of the metal tube contained in the resin bag. Keep the bag sealed.
Turn the key at the end of the metal tube to empty the contents into the resin bag. Knead the bag until the resin and contents from the tube are completely mixed. It takes a few seconds to do this.
Brush a layer of resin mixture over the damaged area. Lay the fiberglass cloth over the resin layer.
Cover the fiberglass cloth with a layer of resin. Keep the fiberglass cloth smooth and flare-out the edges with a brush to create a smooth finish.
Clean completely the area around the crack or break. Use acetone or rubbing alcohol to rid the area of road grime.
Cut a piece of fiberglass cloth slightly larger than the area requiring repair.
Put on gloves. Saturate the fiberglass cloth with the cyanoacrylate adhesive. Place the cloth over the damaged area. Smooth out the fiberglass cloth so there are no ridges or bumps. Use a gloved hand for this.
Using a brush, cover the fiberglass cloth with the accelerator that came with the cyanoacrylate adhesive. The accelerator reacts with the adhesive to harden it within a few minutes. Once hardened, the repair is complete.
