Hello! I love seeing all of these beautiful vintage pieces brought back to life! I have a vintage court in black coming next week and am going to try my first dunk and conditioning! I've been reading your helpful posts about the process and have one question about restoring color to worn piping. I know that the conditioning process will go a long way, but I'm wondering if colored cream polish (like Kiwi) are okay to use for small color touch-ups. I've seen that shoe polish is a hard no - why is that? Could someone provide more information on that? Thanks for all of your help!
I can’t answer why shoe cream is a hard no but I use Fiebing’s Resolene in black on my Faded edges and it blends right into the black leather. I purchased it off
amazon for $9 cad. I apply it after the bag has dried from a dunk but before I start conditioning the bag. Make sure after you apply it, its dry. Ive attached a before and after of the edge of my recent CC rehab that I posted on this thread so you can see What the resolene did for my edges- hope this helps
oh and ps: you only need to do a couple thin coats (1 or 2).If you do too many coats, its gonna get rubbery in texture. Also, I believe the leather dye that a lot of rehabbers use on their vintage
coach bags is the Sapphire brand one if I remember reading that correctly- so you can always use leather dye if you don’t wanna use the resolene

Good question, I would like to know why,too. I used Saphir black color cream to touch up the worn bottom pipping of a bag, it is for my personal use and won't be for sale. It works very good, after dry and topped with Renapur, no color transfer when tested with a white microfiber towel. Saphir color cream basically is just good shoe polish, is there any problems waiting to happen?
Thanks.
I don't know about Saphir shoe polish but I remember reading that some shoe polish brands may cause color transfer and will stain your clothes. Also some polishes may change over time and the colors might not stay a good match.
I always wait until I have completed the rehab before deciding whether or not to touch up the piping because so often it isn't necessary after dunking, conditioning, and finishing with Black Rocks - especially with a dark-colored bag.
See the before and after pics of the piping on this black Blazer Bag 9830 that I recently rehabbed, there was no need to touch it up after rehabbing. Over time the corners may fade and start to show signs of wear again but I just apply some more Black Rocks and that usually takes care of the problem.

I don't think Saphir is the same as shoe polish, as I remember it. Most shoe polish is like a paint that sits on top. I don't know if conditioner will soak through to the leather through it.
Thanks for the reply, now I know why.
So for our friends new to rehab of glorious full grain leather, you will see many of us have a wide variety of products we have tried. Best of luck experimenting and enjoy !
I have used a Saphir product Juvacuir that is basically a leather recolorant. Basically a dye touch up. I used it on a black Plaza that was in excellent shape other than just looking slightly faded over the entire bag. I believe I let it set for several days and put a light coat of Blackrock on it, with no transfer problems. I was and still am super pleased with the result several years later. I have not used their shoe creams here yet. I know someone here used their red shoe cream on a bag.

geek alert*
I found an article discussing shoe cream versus shoe polish awhile back. I will have to see if I can find it and save it and post here.
As best I can recall, a resin product is needed to “carry” the pigment of the shoe polish/cream color. The quality and quantity of the resin can vary. Waxes/conditioners are added and vary as well. As was noted, inexpensive supermarket brand shoe polishes use cheaper resins/conditioners in a ratio that coats the leather, more like a paint. And may have acrylics, that act like a paint. Once a layer of a product that acts like paint is put on top of full grain leather, the pores are coated and cannot accept conditioner. Pricier products like Saphir shoe creams, for example, use higher quality ingredients with a higher ratio of conditioner so the the full grain leather is not compromised.
I have had mixed results with the typical conditioners used here with edges/piping. I have been persuaded by recent results on a BT NYC bag to try a little more CPR and Renapur before using a pigmented product.
That being said, I know someone who took a Sharpie to the faded piping on an other wise great looking Beekman Brief

ETA: Using a small quantity of a leather product to touch up a bag may be fine. It took me a while to understand the nature of vintage full grain leather and how to fully enhance and support it.
And a word of caution, writing this post just reminds me there are YouTube videos out there with people doing things to vintage Coach that make me want to cry. Do what you want, just be informed.
