So I pulled the carpet back on a truck I got a while back, (always have to take stuff apart), and it seems I have a windshield leak that has drenched the factory jute padding and rusted the floor badly with a few pinholes starting. After I fix the floor I want to put the carpet back with some sort of padding-sound deadner so I looked at Dynamats site and OH MY GAWD that stuff is expensive. Anyone have an alternative I could use? I don't care so much about the padding as the sound deadner. Thanks.
