For those who have water leaking from dash...
Once you get them changed, use Rain X a lot.
I never have to use my wipers on my daily driver and I'm hoping that makes the new seals I put in last another 10 years.
BTW, every heard of "Micro Mesh"?
The little black rubber sanding block that comes with it seems to be made from the same material and it makes a good seal material and you can do it with a little upgrade on the thickness.
But like you know, NOW you can buy the kit and do it like that.
