Early tests were promising but I need a good run on a cold morning and its been such a wet winter!
I guess it will also help keep the water out as well!!
I get a water leak from that point, it is caused by spray from overtaking or oncoming traffic, especially HGVs on a fast A road, hitting the side of the car and getting in at the back of the door, puddling on the box section sill under the door.
