Hello

I have a small rub spot on my new branding young chair...about the size of a dime. They sent me a small bottle of the dye to try and touch it up first before we go to more drastic measures. Any tips for applying it? Heat the leather first? Small q tip or corner of a sponge to apply? Air dry or hair dryer between coats, or should one light coat do the job? It's a finished leather so assuming its an acrylic dye...any other pointers? They didn't send any type of instructions so I'm just wanting to do all the right steps.
Thanks!
