Reddit mentions of Fiebing's Leather Dye - Alcohol Based Permanent Leather Dye - 4 oz - Black

Modern leather has a top-coat that is essentially paint. From your photo, it looks like only the top coat has come off, the leather seems ok to me.

When this happened to my E46, I re-dyed it with black leather dye, then a new clear top-coat.

Here's what I used:

Warning: a little goes a LONG way. You barely need to use any dye. Likewise with the top coat: do a really thin coat, let it dry, and see how it looks. Apply additional coats until it feels right. Don't overdo it, and don't lay it on thick.

I also used a paint brush for the resolene ,and did 3 coats of the dye(probably depends based on how bad your's is), and Three Coats of the Resolene, and let it dry between each coat and overnight before using it.

Good job (although I don't think you'll need that much maple ;) .) And hey, if you're crafty and feeling like making some guitar tools, you can use some of that maple, epoxy and a single-cut file (medium or fine) to make a fret-leveling file! I always keep some pieces of HD maple laying around, it comes in handy for all sorts of projects (plus it's strong and cheap!)

BTW, here's a link to Keda Dyes on Amazon, although they're available from their own site as well. The packets are small, but it's super concentrated (as are most powdered aniline dyes), so a little bit goes a long way. For $13 shipped, you might be interested in trying them out.

Here's a link to Fiebings Leather Dye, if you're considering giving that a go. Note that it's alcohol-based, so you can thin them out with alcohol if necessary (they're pretty heavy colors, so thinning would probably be a good thing; you can always add extra coats, but you'll have a lot of sanding to do if you put on too much!) Woodcraft and Rockler both carry some dyes as well, and Woodcraft is just a great place to shop anyway.

I love love love leather dye it really is so easy. I have dyed coats, purses, boots, and a pair of pants so far. I use Fiebings Leather Dye amazon link. There are lots of tutorials out there but I'll tell you what works for me. This is for boots because I wanted them to last, purses coats etc were a lot less steps but anyway!

0-I didn't do this step because the chemical is illegal to buy in California but if you have a coated leather piece, something that's really shiny is usually how you would tell I gather, you would use a leather stripper here. But again I never did this.


1-Wash with Fiebings Saddle Soap


2-After it dries paint on your leather dye. I always did two coats although a lot of times it didn't need it.


3-After that dries buff the item to remove excess dye. If you forget to do that (like I do sometimes) dye will rub off on stuff.


4-Coat the item with something to perseve leather. I use either Obenauf's LP Boot Preservative or Obenauf's Leather Oil


That's it! And I definitely find the item looks a lot better after dye. The Obenaufs makes leather look amazing. And it's not animal oil so I like it a lot more than mink oil say.

Oooooh. Yeah, liquefying the polish makes a lot of sense. I would be more inclined (for safety's sake) to put it in a shallow bath of hot water, but that makes a lot more sense.

Yeah, I would put black polish on and rub it in real good, then buff it, then put neutral on and use the lighter to burn it off. It put a really nice shine on the boots, but after doing this for two years or so, they started disintegrating. I was young and stupid, though.

Nowadays, i have a good routine for when I have scuffs on the leather. I use deglazer over the whole surface (fiebings is the good brand), then let it dry. Then I use leather dye (also fiebings) and apply it all over and let that dry. You have to be careful to apply it evenly, though, or you get streaks. Then I use lincoln stain wax generously (applied with a sponge or brush), and then buff the hell out of it.

This is the only technique I've found to really take care of scuffs, though. Polish (no matter how generously I apply it or how many coats) rubs right off the surface.
