Some Misgivings
I have used NP-1 since 2004 and appreciated its good characteristics: strong adhesion, long lasting, and the ability to bond with many surfaces. Unfortunately, the surface it bonds with best is whatever you are using to tool or smooth it. Unlike most caulks, using you finger or a caulk smoothing tool will not give good results. Using a tooling lubricant such as water and detergent or diluted alcohol can compromise its good characteristics. If you watch the manufacturer's instruction videos, you will notice they make no attempt at smoothing the caulk, but rather just leave it as it comes out of the tube. If that works for your application, this is a great product. If you need a smooth, tooled bead, I suggest trying something else.

Great product
The best caulk on the market (in my opinion). I used it around a leaky window on my garage and it works great! Haven't had any more issues with the window leaking.
