Just wondering,
Why do you think more builders here do note use Robbie O's method of pore filling? Personally, I think it is the perfect pore filler. Just make sure to use fine sawdust. You can also, if using multi colored wood (larger strips of each color) get dust from each color and fill with exact match.

Is time the issue? Faster to spray z-poxy or something else? This method, even if you fill with different colors of wood, does not take long and the results are great.

With multi-colored wood, like Mac ebony, BRW, Ziricote and such, it would be near impossible to try to do a clean fill job with shellac and multi-colors of dust. And even if you were patent enough to keep clean (meaning the right color in the right area) the tome it would take would be excessive I would think. not realistic in my opinion

To the main question.

I assume you are referring to the shellac and dust method, As Robbie also uses and teaches to fill with Zpoxy. In fact I believe he uses zpoxy much more often than dust and shellac. but I could be wrong. Anyway the reason Zpoxy or other finishing resins came to be popular is ease of use combined with the color POP they give the wood.

The shellac and sawdust method has worked very well for me over the years and is much easier and cleaner than epoxy. However, it doesn't pop the grain like Michael said. I like using it under high solids products like urethane and polyester. These products already pop the grain due to their amber type color.
I have on occasion used it under French polish as well.

When I said clean I was referring to keeping dark dust in dark area and light dust in light areas if trying to color match the dust on multi-colored woods. Not in keeping the work neat. The dust method is a great method somewhat kin to pumice filling.

Then the effort of rendering the dust to match is difficult enough when sanding or griding from muli-colored woods like BRW, Mac Ebony or others. It certainly can be done but seems like a lot of work for little benefit

You are correct Michael.

Thanks guys. Just the info I was looking for,
