Sanding & preparing is the important thing, I used a maroon color good quality spray can for the undercoat, after drying sand with a fine sandpaper or steel wool. Then I used a dark varnish with a paint brush for the knots and wood looks, sand and steel wool again for a smooth finish, then a good quality clear coat spray can, about five coats, sanding and steel wool after each clear coat. Mine turned out great just don't get in a hurry.
