What brand of door sill guard to you purchase? I'm looking as well, but I have read reviews of water intrusion. Thanks!There’s been no issue with the sill guards and door seals to date and they were my first addition after purchasing my Jeep in Aug 2018. I’ve noticed zero water, dust, or visible light intrusion around the door seals and sills so everything appears to be tight.
Just turned 21,000 miles and while I’ve not been through deep standing water, there have been some exceptional rains and moderate water I’ve driven through. I’d think if there were an issue it would have appeared at this point, especially with the additional spray created by the additional protrusion of the tires beyond the fender line when I added the wheels.
Hope this helps!!
