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!
