Thanks, guys. I was looking at the Super Blonde on Amazon, it does appear the lightest. Right now, I want to use it on a light tan Alexander, so I'm being cautious.
This is what I use and what it looks like mixed at about a 10/1, alcohol/shellac ratio. The color portrayed is fairly accurate. The felt I used it on was a SB with no discernible color change. I use a 2”, cheap as I can find brush.
