Keep getting dye on back of leather

[Doc Reaper]

I see folks here using black markers, I use a roller to apply edges, it leaves a clean line and not as messy as a dauber. The edge rollers do require cleaning but I’m good with it. 
if the back is to marked use a paint roller (not soaking) to cover up the untidy looks

In times more recently I have seen some edge paint sellers recommend building the edge paint onto a flat edge. I have never found that to be very successful myself and do prefer to keep the edge coat thickness minimal and ironed in to toughen the paint up as well. Burnishing can be a lot quicker and give a similar look on the right sort of leather (mostly veg tan) but can not keep the smooth polished look for as long sometimes. Many products like the crocodile skin products I make can not be bevelled with  hand tools and can not be burnished well in most cases. To not bore you with a whole lot of whys and wherefores I will give you a link to a post I did awhile ago that shows pretty much the process of doing edge painting the way I do it.

 

When you get to the stage where you're polishing the edges 4-5 belts at the time on the buffing wheel, instead of doing that try running a clean cloth with a touch of acetone along the edge.   Depending on the chemical composition of your edge paint it might give you a mirror finish very easily (or it might not, so try it on a test piece).   I think it was acetone anyway, it's been a while since someone told me and I tried it...
