I washed my van today and noticed a fair amount of water got in the van at the double doors on the passenger side. I've noticed the seal is not in great shape for some time.
The bad seal

Here's the rear seal which is in great shape.
The back of both seals look like the picture below
Is this a DIY fix, and if so what materials would I use?
