Part 5/7:
After identifying a leak, Hank detailed his approach to sealing it: he uses a polymer-based sealant, referred to as Polymax, noting that both gray and transparent versions are effective. Hank's pragmatic approach emphasizes simplicity; he prefers using readily available materials rather than overengineered solutions. His choice to seal a viewing port with standard borosilicate glass, bonded with the polymer, illustrates a commitment to functionality over form.
