Using Rhino lining as a keel guard is innovative and easy. Typically, a keel guard is a sheet of polyurethane that is attached to the keel, as a covering, in one layer. Rhino lining is a spray-on protectant that is used for multiple projects; such as pickup truck bed lining, and watercraft foot space. The Rhino lining is a strong poly-urea that protects the hull of the boat from salt damage, sand abrasion, and other scratching hazards.
Sand off the current surface on the keel. The current surface is likely just wax: But leaving it, will not allow the new lining to affix itself to the hull properly. Use the wool sanding pad on the sander to remove the surface quickly. Do not press hard, or the sander might scratch the keel of the boat, and compromise the hull's integrity.
Pour a cap-full of alcohol-based cleaning solution onto a clean rag. Completely clean the keel area of the boat, removing any debris. Repeat this process at least once. Any debris left on the hull might cause lumps in the Rhino lining.
Pour some 3M brand #94 keel primer onto a clean rag. Apply a thin layer of the primer to the keel area, making sure not to miss any spots. The primer bonds with the Rhino lining, to create a more secure attachment to the hull.
Be aware that too much primer can cause the lining to bunch and clump. This will then allow it to be bumped off when the boat is dragged through the shoals or sand.
Stand two feet away from the keel, to protect your clothing from blow-back and staining. Spray the keel with the Rhino lining hose and air compressor. Be careful not to miss any spots on the keel, and repeat the spraying process twice.
Allow the Rhino lining to dry and set for at least 24 hours, before placing the boat into the water or onto the ground.
