I thought I would start a thread around the practice some have taken to of customizing their leather smart covers by using leather oil to treat the outer leather surface -- typically darkening it and giving it a richer, more leather like appearance. (subjective but a lot of comments seem to support this opinion). For those that already have done it I thought we might be able to exchange tips amongst one another and answer questions from other users thinking about doing it. For those own the fence or unfamiliar with the option I thought a separate thread just about this might be a nice highlight of the option, I will point out that there are bits and pieces of advice tucked away in other posts here and there but I thought a new thread might help to consolidate. I will share my experience. I ordered the tan after reading about people doing this and feeling optimistic from some of the photos. I ordered Obenauf's Leather Oil from Cabela's hunting store online and waited 4 days for its arrival. Once it arrived I applied the oil liberally and freaked out a bit because it was very streaky but it was just the leather taking 20-30 seconds to soak in the oil and darken. It quickly was all the same color and after making sure I got some nooks and crannies around the hinge I let it dry. I applied VERY liberally and wiped off the excess per the instructions. I was also cautious around the edges as to avoid the oil beading over the edge and staining the microfiber inter lining of the smart cover. I am overall very happy with the darker, richer brown color. I would describe it as a walnut brown that is very even across the entire cover. I was hoping it would be a bit lighter and a little more "natural" looking. I guess I am hoping that over time as it dries out and gets folded hundreds of times and gets a few scuff "beauty marks" I will like it even more. A natural brown leather ages more gracefully in my opinion with age and looks even better when it has the look of s nice nice worn saddle / baseball mitt / boots / etc. I am less sure about how some of the other colors will age over time. Overall, a huge improvement (IMHO) over the corrugated cardboard color the tan case was originally. Not sure if I like it more than the black but I really do like having something semi-unique. For those nervous with the process it was my first time I ever used a product like this and was very quickly comfortable with the process. I have attached a few pictures grabbed from other random posts that show the result of other folks application on the tan. These photos are very representative of my final result. I am new to posting in these forums so if it's poor form to "steal" photos from other posts I apologize -- just trying to consolidate the discussion for those that have recently done it or those considering it. If anyone has pictures they would like to contribute please add it to the thread and I will take these "stolen" images down. Any questions..?
