Hi John, we didn’t find it a problem coming in under the screen but it looks like it should because of the gap there. We did have it coming in behind the dash and dripping on my legs once in heavy rain but then on another occasion there were no problems, I think this can come in around the wipers. The day we picked our new car up was horrendous rain and going down the M4 there wasn’t much water coming in and the new car was just as bad if not worse so I don’t think you will ever get a dry one except a friend of ours says there's is nice and dry.
I did push a bit of neoprene down in to the gap at the bottom of the screen so that may have helped.
