Rated 4.0 out of 5.0 by Lexc Worked for me
I bought this after seeing it on a website for gluing down soundproofing underlayment. To get it out you not only have to cut the tip like normal caulking but also stick something down through the hole to break a metallic seal. I used a screwdriver and then it worked fine. I think the people writing reviews saying they could not get it out may have missed this step. I gave it a 4 though because it took a pretty long time to dry.

Rated 5.0 out of 5.0 by imnoldtimer The best you can buy
As a professional maintenance person in the business for over 35 years, NP1 cannot be beat for it durability and adhesive qualities. I use it for just about anything that needs a semi-permanent application.

Rated 5.0 out of 5.0 by MADDOG Have not used yet, but was told by a professional to use for large concrete gaps.
The product was recommended to me by a professional that works in the concrete field. I have not had a chance to apply the product yet as it turned colder than allowable for the product application.

Rated 2.0 out of 5.0 by mike OK - but could have done better
I bought gun grade polyurethane sealant. It was so difficult to get out of a caulking gun, several tubes 'backfired' and had sealant material pushing past the endcap inside the tube. This made for some messy cleanup and I lost about 20% of the material. I think it was old material which had partially cured inside the tube.
