Shrunk after directly sunlight exposure
This product does not perform. It shrunk by around 25pct after exposure to heat and sunlight covering the cars Panoramic Roof.

Very good product for multiple applications
They have nice square markings on back side for easy cutting measurements , and the bonding to surfaces in very good , even to primed surfaces . And removal of backing is effortless and peals off easy and clean . Seems like a very good product . Works excellent as well for making new seals for removable floor panels in semi floors .

Easy to install, cheaper and better than other self proclaimed 100% sound proofing products.
The 2022 Honda Civic Sport has a noticeably "hollow" and loud cabin at highway speeds. Honda skipped premium sound-deadening in this trim to keep the car lightweight and affordable. So, instead of spending a couple of thousand more on the trim, I decided to give Siless Liner a try and I am stunned by the results. The difference is night and day. I am very impressed by the quality of this sound deadening foam liner. it took me about 2 hours to completely cover my car's boot.

GOOD PRODUCT // ARRIVED IN ONE DAY//WORKED AS ADVERTISED
The product at least for me worked exactly the way it should have, The adhesion was far better than shown in comments, it was about 45 degrees in my garage it did not budge...I am going to line my subwoofer box next ....
