I've never tried rehabbing this particular bag but I've tried other Legacy bags from the same collection, and I failed miserably. For some reason, no matter what I did generally made the bags worse. I tried to paint the worn colors but instead of the paint covering up the wear, it made it darker as if I had painted it with water. I tried many different kinds of paint and nothing worked. I did paint an entire Legacy bag with wood n stuff leather refinisher but that was after I had dipped the bag in RIT dye. I think that dipping may have made the leather more receptive to the paint. I made a horrible mistake when I dipped in the RIT in that I used the hot water that is recommended and it melted off all the brown edge coating.
I hope your experience is better than mine.
I plan on using Angelus leather paints, I didn't even know that you could use RIT dyes! I watched a few videos that say how you shouldn't color match 100% since the color does get a little darker. But I'll probably be very careful since I don't want to make any mistakes, but thanks for telling me!
