i did shellac on my MBM build, i went for 10 grams shellac flakes to 100ml of ethanol, then added stain.
i let it sit for 24 hours with mixing and then strained it through mesh and sprayed it using a wall sprayer without a compressor
i did 2 coats of each color for the burst i wanted, and then i did 4 or 5 coats of clear shellac (some of them with a brush) all from the same batch.
this actually worked out quite well, and it was on an ash body that i grain-filled first
