You may not have to go full Monty to stop leaks. However, in my case the machine bolts became the problem. I’m sure when the PO installed machine bolts and nuts, that was a good solution. Over time, additional tightening stopped being effective and the screw holes themselves became the problem. Done correctly, the full Monty is a sure thing because there’s no way water can enter.
IMHO, removing the old caulk correctly requires removing the lens. Then it’s just a matter of scraping with a putty knife and finishing with a small wire brush/acetone.

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.

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).

Looking for recommendations for cleaning it out so I can mask off and deglaze with Dow 795. What tools/techniques work best? TIA!!
