So my TD started leaking by the fantastic fan. When I installed it (two years back) I did so with 100% silicone, but it appears to be suffering from the heat cycles, and appears to be the weak point.
I know I can order like 30ft of butyl tape from amazon, but I'd rather buy it locally. My local home depot, lowes and menards dont carry it, but I wondered if I was overlooking another possible source.
Any help on where to find it?
Background info, td is stored outside in Michigan. Anyone local knows what that means, lots of rain, snow, and bad things, lots of temp swings (30-40 degrees in a day is not uncommon). Its tarped over the winter so snow build up doesnt compromise the vent seal. I found the leak just before I tarped it for the winter, and it was a very mild leak. Got the mattress and bed clothes out, and tarped her up. I've checked a few times since the tarp went on and shes dry right now.
