I've messed with more rolls of duct wrap than I'd like to admit, and this ThermaTack spray finally made it easier!What I like -The application is simple, just shake, spray and stick. Way easier than using liquid glue.It has quite a good wide spray pattern. It covers more surface area faster, though it can overspray if you're not careful.It has a strong industrial grade formula which is perfect for HVAC guys or serious DIY'ers.The usage is pretty flexible, it's really sticky and has a great hold on most things.It's also a really great value for money.Be aware - It's highly flammable so make sure you bear this in mind while using and ventilate your space.The clean up is a hassle so if you don't want to be cleaning up, make sure everything is covered in something you don't care for.Bottom line - This spray is a game changer! It's strong, fast and versatile and ready for any project. Just make sure your space is well covered and well ventilated.
