Dye stain does have its downsides

Water-based stain is more eco-friendly than the oil-based equivalent, and it cleans up simply, with soap and water. It also has a shorter drying time, however, so it can be hard to apply evenly. It also tends to raise the balsa wood grain, but it won’t do as much if you get there first. “Pre-wet” the wood in question, wait for it to dry, and then sand it. The stain’s wood-raising effects will be considerably reduced.

On that note: Sanding wood with sandpaper that’s finer than 150 grit is a bad idea if you plan to apply pigment stain. Due to its sizable particles, pigment must attach to irregular features in wood zfffjllh, such as scratches or cell surfaces. Making a piece of wood too regular more or less ensures a frustrating staining process.
Unlike pigment stain, dye stain often comes in powder form. After being dissolved in water, it achieves a significantly deeper color in wood than pigment can, and it doesn’t hide the grain as much. In addition, dye stain can be custom-blended, or even color-corrected after the initial application.

Dye stain does have its downsides. It’s susceptible to fading in the sun, whereas pigment holds its color no matter what. Metalized dye, premixed with alcohol and a chemical that slows drying, is more colorfast than regular dye. Then there’s oil-soluble dye, which can be used to adjust the color of an oil stain and deepen its penetration, or to add color to an oil-based clear finish.Find more Information by http://www.balsafactory.com/basspolywood/
