Great stuff! I use it with mesh drywall tape and once it's cured it's really solid. I can see where this stuff would have many uses but for sealing A/C ducts, etc. it's awesome. I used a putty knife (and my fingers sometimes) to spread it over the tape or in tight corners. It fills gaps well and seems to stick to just about anything. Water cleanup makes it really simple to use.
Great product.

Worked well on dealing up my furnace duct. Easy to use with a brush or putty knife.
