Splatter dying and sealant inquiry

[HanTark]

Hi all. 

I posted this question on the wrong board.. so I'm trying it here:

I'm working on a custom wallet project with a splattered dye job on the leather and I need to know the best black dye to use that will stay put on the leather (and not run over time) as well as the best sealant to protect the splatters from running together and/or rubbing off.  Since  this leather will be used for a wallet, it'll get a lot of use and needs to be well sealed.   

FYI, the dyes I've tried so far are:

1)Fiebings Black Leather Dye

2) Even tried Fiebings Edge Kote for a more opaque look. 

The sealants I've tried are:

1) Fiebings Acrylic Resolene (I've tried rubbing this on gently but it makes the splatter spots run)

2) Bowling Alley Wax (I've used this for years on belts and such but it's not protecting the splatter spots over time. They all blend into the leather making it look dirty...) 

Thank for your help!!
