Veins shaped lines on my nappa leather door panels

Greetings,,

I own an F90 M5 which comes with nappa leather interior.

I recently went to fix some tint on the windows of the car, and after the installation process was completed, i noticed some vein looking lines on the door panel leather just below the window.

it look like leather has absorbed/ drank some water and go affected by it. I dont really feel difference while touching it however it can be spotted looking at different angles using sun light mainly.

i kept it to dry but it doesnt seem to return to original shape. i used some leather cleaners and conditioners, they made it a bit look cleaner and better but i still can recognize those vein shaped lines / a bit darker areas.

I would really like to know if there is any possible way to fix such or if such problem has been already faced earlier with some BMW/ or different car brands.

below are some pictures showing what i mean.

thank you alot

looking forward to hear from you

The ridgeline is water damage that swells the leather.

To get rid of the water damage ridgeline, Hydrator-3.3 is used to rehydrate the entire panel thereafter Fatliquor-5.0 follows through to soften up the leather with strength.

Here is the recommended Kit-Af3

I am pleased to answer any questions you may have.

I can walk you through with online coaching too, as an option.

thanks alot for your reply, i will proceed with ordering it soon, however it gave me an option regarding mixing it with distilled water prior to use.
how is it related to the order by being an option that needs to be ticked?

and is there an option to have only the hydrator and fatliqour sold separately? as it seems i wont be needing the full set.

regards..

Kits come with concentrates in the bottle that will need to be mix and fill with distilled water.

thank you, i have ordered them separately as mentioned above, will try them and show results once they arrive.

just one question, should i fill the bottles that i ordered completely with distilled water prior to 1st use?

or water needs to be mixed separately each time i want to use the products?

Mix and fill only once, and they are ready to use.
