I’ve used 795 and it had a longer (and welcome) working time vs yer’ basic silicone. It cures easily within 24 hrs to be rubbery but not gooey, lovely stuff. I did have some cheap and aging GE eavestrough sealant ‘with silicone’ that would not cure properly. Thought I’d use it up but it did not work and made a mess. Well, I made a mess…
Your temp fix might be to cut out the old sealant from above (with a razor or box cutter type blade) back to the plexi and frame, to ensure a large trough, mask, and re seal by caulking the gap with silicone - 795 or otherwise. I’ve used a syringe to force 795 deep into gaps narrower than the caulking tube tip. Works well.
