A couple people here used Saphir products to help out and use on white bags, which I believe you asked about. Just do a search of this thread and Saphir.
I sold my original red rambler and kind of regretted it so I went on the hunt for another. I thought the search was hopeless until I found one on etsy but it was in poor shape. I bought it, gave it a bath and since it was faded and scratched I thought I would give saphir a try. Well she looks pretty good now lol.
I don’t want to overwhelm you with a lot of product info, but I am really happy with a few Saphir recolorant products. While they are more expensive, they are created as leather conditions and recolorants, to enhance the leather. I get the impression cheaper products tend to have more acrylic content, which could have a sealant type effect on the leather.Now someone posted using a product, Saphir recolorant creme called Surfine in #11 that got a nice result for red. I will likely pick it up when this needs help.
