Cream or white Latex paint covered brushed on with wood stain works the best for that situation.Looks nice. It looks like your using a grinder or something to shape your pieces.
One trick I use is glue sintra or a plastic together like plywood, and then grind it, and it doesnt have a woodgrain texture.
Or you could whipe some bondo cream on it, to fill in the woodgrain.
As always though, looks great.
