Ani Yeshi worked on removing the old caulk...but unfortunately we purchased the wrong replacement! We'll pick up the right stuff tomorrow. Many clear caulks apply white and dry clear in a week or so. Our experience has been it is often not the case. The white remains pretty white. So we'll hold out for a caulk that applies clear....the fit of the plexi is good enough to protect from all but the worst rain, and if we're lucky, it won't rain...
