Tom, I have hull 626, and also have the bronze port lights. I like the classic green from light corrosion, but I’m sure there are numerous products that will restore the original bronze color with ample elbow grease. For the glass, I imagine Windex would suffice. Incidentally, I love the look and functionality of opening ports, and would not have purchased the boat without them.

I have a M-17 #624, with four bronze (?) functioning port holes. Dose anyone know how to clean them properly?

Thank you, Tom Budington
