Kudo's for doing all you did yourself! That's a cool photo of Salma, hope to see the "after" taken coming out of the shop. Here's a thread I found searching "butyl" because that's the sealant you must use, not acrylic or whatever else. On this thread is says use butyl tape not the liquid caulk. I bet you could do it with a helper.
