I seem to be grain-fill/stain challanged! Are you using water based grain filler? Hi Terry - I have used both water-based filler and solvent-based filler, and either way, sanding the stuff without sanding thru the color IS a challenge that requires constant vigilance while sanding. I wish I had a magic word or two to pass on to you, but I don't. As I mentioned in an earlier post, sanding the filler in the exact same manner that you sanded the bare wood is a necessary starting point. When you don't use grain filler, how many coats of top-coat do you find is required to get a level finish - or do you live with the grain depressions in this approach? Naturally all woods are not identical, but generally I would say that mahogany sanded to 220, dyed and sealed with at least a 2lb cut of shellac, will require app. 6 total applied coats of water-based material to fill the grain. I just sprayed one last week where I stopped at 5 total coats of water-based, and there is the ever-so-slight amount of grain showing, a look I have warmed to of late.

First I would use dyes to get the color I want, then seal them with a wash coat of shellac. If I AM gonna use filler that would be next, although oftentimes I don't use it. Then, if necessary, a few very thin toning coats (tinted shellac, usually) on miscellaneous pieces to even up the color ( and, BTW, this does NOT have to make the finish look muddy, as you earlier suggested!), then on with the coats of finish.
