RTV Sealant
RTVExcellent durable waterproof adhesive.Used this RTV to seal up a hole torn in a tennis shoe.Use a drywall spreader to apply. Dip the spreader in soapy water to prevent RTV from sticking onto the spreader. Apply RTV generously and smooth out for a clean finish. Let dry 24 to 72 hrs.

Very pleased with sealant
Very pleased with this product. Used it on a couple of projects and it has done the job. Good for filling holes to make things watertight with no pressure. Pro tip: This stuff is sticky so if you are having trouble getting this everywhere use a damp paper towel when applying it won't stick to items that are wet and makes clean up a breeze. Once dry in 24hrs fully waterproof.
