Hi Alden,
Thanks for reaching out and for the detailed description.
Yes, both of the issues you're describing are common on the JK, and the
body-side sealing approach is designed to address the type of water
intrusion you're experiencing.
The continuous bead of water you're seeing running across the plastic
door-sill area is a classic sign that water is getting past the door seal
and then traveling along the body before finding its way into the cabin.
The rear hardtop window leaking from the upper corner is also a common JK
leak point.
The important thing to understand is that these leaks can appear to come
from completely different locations, even when they're related to the same
underlying sealing problem. Water can enter at one point and travel along
the weatherstripping or body before you actually see it inside the Jeep.
The root cause comes down to the factory sealing design. Unlike most
vehicles on the road today, the Wrangler JK does not have a proper
body-side sealing surface. Instead, the door seals are trying to compress
directly against painted metal. Since painted metal is not a consistent
sealing surface, small gaps can develop around the door openings, allowing
water to enter during even light rain.
That's why simply replacing the factory door seals often doesn't solve the
problem. You're replacing the seal, but it's still trying to seal against
the same painted metal surface.
Our body-side weatherstripping creates the sealing surface that the factory
design is missing. It allows the existing door seals to compress properly
and consistently, closing those gaps and preventing water from getting into
the cabin. It also helps seal out outside wind and road noise, making the
cabin noticeably quieter.
For the rear hardtop window, the kit also includes the appropriate
weatherstripping to address the hardtop sealing areas. The goal is to seal
the Jeep as a complete system rather than chasing individual leaks one at a
time.
So yes—based on everything you've described, I would absolutely recommend
the kit for your 2017 JK.
