This is my first step when finishing walnut since the wood varies in color so much and would normally fade over time. The dye does not obscure any grain and you have total control over how dark to make the wood. Yes it raises the grain and requires you to sand lightly before the top coat (garnet shellac looks terrific), but it does a good job on coloring sapwood, lasts forever (in the shop and on the wood), and is easy to apply by brush or rag. I suppose it works on other woods but I generally do not color wood and use this on walnut only to equalize the project and make the color permanent.
I own this product.
