    Was this supposed to come with nozzles to attach and actually USE this product? Because I didn’t get anything of the sort.

    It does its job but once you get it on your hands, youre doomed. Soap and water wont get it off, unlike other brands Ive used such as DAP. I had to break out the paint thinner because trying to wash my hands in the sink only made it worse. This makes it very difficult to work with.

    Product must have been old because it was difficult to get out of the tube using the same caulk gun Ive used for years...
