My previous owner used 5200. For me, it was more like 2.5 hours per port. I did all this over about 4 trips to the coast. Would love to find the guy who applied that stuff and beat him with a fresh tube of 5200.
I used simple white silicon to replace - it collects dirt a bit on the outside, but is very easy to clean with your thumb and will be very easy for the next guy.
