Alex is an acrylic/silicone mix, stays flexible, handles expansion well and is paintable. It is used in homes with vinyl windows and can be sanded/re-applied over itself. The ProFlex is a great product, but the outer bead of sealant on the windows is just an added protection. The butyl tape would be fine on its own. I have no worries using Alex as an extra protection.
