Oh my. I was hoping that I wouldn’t have to go full Monty on them. Any recommendations on removing the old caulk? 

Someone posted something about toothpaste but I’m not sure what it referred to.

The first thing I noticed in your photo was the screws, which on my 42 Custom were the main sources of leaks.  Per the SOP from this list, I eliminated the screws and screw holes by replacing each lens.  With the lens removed, I cleaned up the cavities first using a putty knife to remove old sealant then using wire brushes, shop rags, and acetone.  I also filled the screw holes with an epoxy mixture.  Once the holes were filled and the cavity was fully clean, I applied 3M double-sided tape and put each replacement lens in place using the “tape hinge” method.  After that, the Dow 795 is used.  My windows haven’t leaked since (10 years or so).

Here’s a close up of the old dried out - and missing in places - glazing on my 1980 C&C MKI. Looking for recommendations for cleaning it out so I can mask off and deglaze with Dow 795. What tools/techniques work best? TIA!!
