AcquaSeal™ Water Based Acrylic Concrete Sealer

The sealant is excellent, the 5 gallon container that it comes in however is next to impossible to open. After many attempts to 'unscrew' the cap, the chat bot on the site told me to go purchase a special wrench to get it off! That wrench should have been included for the price paid. I ended up punching holes in the top with an awl to get the sealant out.
