Nice, they've now matched Menard's price with the 11% off.
So this is even sweeter, especially better if you have the Amazon Prime visa and can get 5-6% back

Well worth the money. Easy to apply and havent had an issue in years. Better than caulking and foam imho.

You should be using items that are made for that such as Plumbers Putty. I doubt this is waterproof

What is the advantage of using this over foil tape? It looks like a big mess that I doubt is as effective.

Speed of application and long term durability. I used many buckets of the stuff working on commerical/industrial HVAC installs.
