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
