The first thing you missed was turning off the caps lock. Don't do it again.
As for the stain, alcohol-soluble stains will work as well, use a brown rather than a black as your dark base, and be very careful when sanding back, to make sure you don't sand through the veneer. If you're worried about spoiling the veneer, just use a stronger amber coat for the first dye, sand back a little and go from there. Just do what you feel comfortable with.
Sorry people I clicked on the wrong reply box. Lets try this again. The caps lock is off. I will use the dark brown dye to do the base coat. Thanks for the info...Mike...
Sorry people I clicked on the wrong reply box. Lets try this again. Yes I have plenty of veneer to practice with. My original question was to help me make a choice, water based or alcohol based dye. Thanks for the info...Mike...
