Review: Used this to dampen sound on dishwasher - Used this instead of the cotton blanket to insulate and deaden sound on an already whisper quiet dishwasher. Just peel and press on. Doesn’t smell of chemicals. Works just as good if not better than the blanket to quiet sound plus it’s easier to slide the dishwasher back in and out to deal with repairs. Review: Ottimo prodotto - Molto adesive, ho rivestito l'interno delle portelle auto per migliorare l'insonorizzazione.
