I love sourcing product and talking to people. I ended up on the phone one day with a salesperson at the company that makes Goop and I found out that all the differently labeled Goops are the same product.

Goop used to be sold in the hardware store in the adhesives area, usually found in the paint department. At some point someone in another department, say, plumbing, wanted to carry Goop, and their department buyer called asking if there were a Goop for plumbing. After a few departments had done this, the Goop people realized they could sell more if they were to label it especially for the department they were selling to.
