Good
Did the job of sealing up gaps in my home. I coated it above wire mesh wool for extra peace of mind and so far so good..nothing has chewed through old entry points

Perfect for the job, if a little pricey
Perfect for the job, although I wish it came it smaller sizes as I still have about 3/4 left and it's quite expensive.

Blocking Mouse entry
The product was delivered promptly. It is simple to use and (so far) effective. The metallic content should deter any nibbling.

Not dry after 9 days and is still soft
It’s been 9 days since I used this product and it’s still soft and wettish, I used it for indoors and not sure why it’s not 100% dry yet
