I took out the mats/ carpet - & there is a thick matt attached to it, but there is also a white foamish material covering the floor that was under the carpet. Looks like insulation or more sound deadener.

1 of the matts is dry now - the other still has a way to go.

My sunroof does not open. so I can't get at the drains. I'd hate to pull down the head liner & not be able to get it back up.
