you have a link to that? might be good for my upcoming 4xe grey leather.
any exterior recommendations also welcome. the tree sap here is a KILLER.
tree sap inside the car? lol you have bigger issues to address 
few options here - Leather Coatings | Car Supplies Warehouse
honestly it gets EVERYWHERE so i wouldn’t be surprised.
a lot of products there. which one specifically has a ceramic coat for leather?
Gyeon Q2 Leathershield | Car Supplies Warehouse or CARPRO CQuartz Leather 2.0 Coating | Car Supplies Warehouse
i used Gyeon on my M5 last weekend
I think the coating will help but it won’t be enough. I had a major issue with my white car getting covered in it every day. It took forever to remove them even when using alcohol to soften it. I finally gave in and put it in the garage (I was avoiding the garage for another reason). Now if I come back from a drive and see a mark I immediately spray it and wipe it off. I’m not dealing with that ever again.
