The thing about 303 is the UV protection. Nothing can top it and that is very important - at least it is here in Texas where the brutal sun can play havoc on leather. The label says it is approved for leather as well.

Our seats are coated or "treated" leather, not natural leather as was the case with auto interiors many years ago. I suppose some exotic cars and a few Euros are still made with natural leather but most modern vehicles use "treated" leather. If you have natural leather seats, I would not use 303 but rather some real good conditioner products such as Leatherique or Lexol. These products are made to "feed" the leather through absorbtion. The very reason "treated" seats are treated with a vinyl like protectant is to resist absorbtion. Therefore, the leather conditioners will loose a great deal of their effectiveness if they can not penetrate to the leather itself. Some will get through but if the "treated" leather is doing its job, it will resist anything going down to the leather itself, whether it is good for it or not.
