In my TV cabinet build thread I described a problem I had with some stain taking too much and having dark strips in the glue up. I got a ton of great advice on how to avoid this, so I thought I would run a test on the underside of the new top.
The first pic shows the dye alone, with shellac, with sealer, and with conditioner.
The second pic shows these after the stain has been applied.
Note the stain only and the conditioner are closest in color with the shellac sealing out the most stain followed closely by the sealer. In both cases, for my taste, it sealed out too much stain leaving too much of the yellow cast of the dye showing through.
The big failure of the test is that it seams there was no part of this wood that soaked up too much stain!
