Sorry, but if you have that much water INSIDE the car... you shouldn't be blaming rusted out floor panels on the sound deadening material.As we all know the #1 thing that kills our car or any car for that matter is rust.
The matt products when they get wet, and they will just retain moisture and rot the car from the inside out. When I did my research on the Lizard Skin this will not happen, car is cooler and quieter. Buy the kit with the gun and mix and spray, that simple cleans with water and you don’t need a respirator when applying it safe and 0voc just my .02

In fact, most of the sound deadening mats I've seen would actually block the water from contacting the metal (depending on installation and coverage)
