2 excellent videos, great job
Nice res too on them as well.
I have the same gasket on my kegs. My 2 kegs are almost 2 years old and the gasket is still ok, shows some wear from being closed most of the time but no problems. The only time I get smoke leaks is when I'm running a probe wire into the keg. But that's just when the smoke is heavy in the beginning. My guess is since your lid is not as heavy, the gasket will hold out even longer. As far as rust is concerned, I keep them under cover so no big concerns there. Any cooker is likely to show some rust or a little wear on it's parts if you expose it to the elements. Can't wait for your next vid.
