Finally! Finally, I have found a blotch control product that works. I thought I had tried em all, but not so. I bought a bunch of Hard Maple to make a toy box for a favorite Niece, and I hadn't used Hard Maple before. Blotches like crazy. Dang! I was using a dark Walnut and dark Cherry stain and the result was beyond ugly. It was as bad as an old gunstock I tried to stain a few years back. Hopeless. So...a bit of research on a woodworking forum I frequent, and it was suggested that I buy the liquid blotch controller sold by Charles Neil. So I did. Wasn't getting anywhere with anything I had tried so far. I even read the directions and applied it as outlined. And it works. I had to blend the stain darker, since the blotch controller does lessen dye penetration.
Just thought I'd share this info with you.
