No, Doc Blue is not the same as Stans. While both are sealants used to repair punctures in tires, they are made from different materials and have different properties. Doc Blue is made from latex rubber and is designed to be used on inner tubes. It will not work well on tubeless tires. Stan's, on the other hand, is made from a synthetic polymer and can be used on both inner tubes and tubeless tires. Stan's also forms a stronger bond with the tire than Doc Blue does.
