How can I achieve a smooth finish on my wood project using sanding gel stain?

To achieve a smooth finish on your wood project using sanding gel stain, start by sanding the wood surface with fine-grit sandpaper to create a smooth base. Apply the gel stain evenly with a brush or cloth, following the wood grain. Allow the stain to dry completely before lightly sanding the surface again with a higher grit sandpaper. Repeat the staining and sanding process until you achieve the desired smoothness and finish.
