Default X100 undertray rubber strip replace

My front undertray is reparable but the rubber strip/lip that sticks down across,it is a goner. Looking for a replacement. I don’t even know what to call it. Any help is much appreciated. Thanks!

There is quite a number of very similar rubber extrusions available by the metre. I assume it's only purpose is to disturb the undercar airflow in some way.

Does anyone have the exact measurements of the profile on that rubber strip?

I have found sevral alternatives that seems to be very close to an original strip among water barrier strip/seals for shower/bathrooms with very little to no trimming.

I found fender flare cover rubber strips that are 1 1/2 inches deep. It may be softer than the original strip, but I think it will look fine. I’m going with that. If anyone finds the perfect stock-similar strip let us know. Thanks!

I was about to put the undertray back on after replacing my front bumper cover then spotted this post. A photo and a drawing below. You won't be surprised that I'm not a draughtsman but it's as accurate as I can get it.

Length: 860 mm
Height: 14 mm
Small lip: < 2mm (probably unecessary but it's the small lip you can see on the bottom left in the drawing
Depth: 13 mm
Lip depth: 4mm

I have way too much if you want to buy some  from me at my cost plus per foot plus shipping. It is soft rubber, so it won’t be damaged if you bottom out on something… plus easily trimmed to shape edges as you like.

It has un-needed adhesive on back side. I’m not sure if I will rub something on it to eliminate stickiness(Oil or Dirt maybe)… or stick something on there.

Hi Othodoxie. I’m going to sand the mounting recess with about 180 grit paper and use two-part epoxy to mount it from the top sideways edge. I’ve had good luck with epoxy for adhering.
