Review: good stuff, I used this for a building we ... - good stuff, I used this for a building we put up, the wrap did as it was supposed to, one thing you should know is a few days the temps were in the low 30's here, we had to use a hair dryer to heat up the area so the wrap would stick, on warmer days say 50 and up it was fine. we did 3 large windows and a man door with the product. it was very sticky and once it was stuck to the house wrap it was there. For the price I would suggest this product.
Review: Good product - It is good window tape works great

### ⭐⭐⭐⭐ Good product
*by M***A on June 3, 2022*

It is good window tape works great

### ⭐⭐⭐ Not for auto sound dampening
*by D***O on May 12, 2015*

Many people are buying similar products for auto sound deadening. This is not a good choice for that. The material is thin, the backing is not very sticky. The top surface is more of a aluminium plastic. Not malleable to retain grooved shapes etc. As a window wrap it is okay. Still not really sticky enough for outdoor construction real world situations.
