This is a rating for the interior paint, not the storefront. Not sure if it's watered down or what but you have to expect to apply 2-3 coats. You're better off using Behr for coverage and concealment if painting over existing paint. It may be $40-$50 cheaper but you're going to need 2-3× more paint than Behr.
