Hi, i am new to leather dye and I have been searching on the web, but I am pretty confused now, so here I am asking for some advice and opinions.
1) What kind of sealer can I use on water-based dye like the Eco-Flo? I got a bunch of Eco-Flo water dye here and some Fiebing Resolene that i never used, would that work? I also have Angelus leather finishers matte and acrylic, are they also any good?
2) Can I dye over a leather that already has a dye? After searching the web, I found solutions involving rubbing alcohol or white vinegar, but I am not sure if they would damage the leather. Maybe I could just keep them as is and they will still sell even if they do not meet my personal taste, who knows.
3) If we can effectively dye over an already existing dye, what techniques are you using to properly prepare and clean the leather to accept the new dye?
Thanks you in advance for any advices!
