In my case I didn't "folded up" the Dynamat pieces, so water can flow over them and meet the existing super thin gap between the chassis tubes and the floor steel plate. I mean I installed them flat on the floor and just getting a little bith under the chassis tubes, but I hope without clogging these thin gaps between the floor steel plate and the chassis tubes.
I still haven't drive under heavy rain (Madrid, Spain, where I live is really dry) so I can't tell you if the Dynamat is avoiding the water to flow out properly...
