Good product.
Works well, did both the inside and outside of my F150 front doors, couple of layers on the outside. Super sticky!! Use small sections as if you try a large piece, once you apply it isn’t coming off if you miss align it. Helped my stock speakers sound.

Siless is the best
Siless products are top notch. This is the first time using this particular product. I’ve always used the 80 mil butyl product. Wanted to use this one for more of an insulator. Does work well. But there were some spots that still sounded hollow, and I went back and put the 80 mil butyl product on top. Works amazing. But I would suggest to use the 80 mil butyl product on real hollow sounding areas first, then use this product to cover the entire area with it. Some of negative reviews, in my opinion, are from improper installation. Once this stuff goes down, you can’t peel it back to adjust it, because the glue is that good. If you do, peel it to adjust, the integrity of the product is ruined. My suggestion, if it’s not lined right, don’t peel it to move it. Just get another piece and cover what you missed. Don’t matter what it like, it’s getting covered with carpet or plastic panels.

Faire attention lors de la pose colle reste où elle fait contact
C' est quand même facile a installer mais il faut faire attention lors de la pose,car la colle adhésive est très efficace,si elle fait contact a un endroit non voulu c' est trop tard. On ne peut pas l'enlever et le recoller,la colle reste là où elle a fait contact, alors il faut prendre une autre pièce
