The technical bulletin for it was last updated on 3/21/05, so it's been around at least a year and a half. The product itself is just 100% silicone rubber. DAP is great at marketing because they have at least a dozen different packages that they sell their silicone sealant in. My guess is that they only provide so many packaging options for the exact same product because it makes it easier for consumers to know for sure that it will work for what they are looking to use it for without having to actually turn a generic package over and do some reading.
