95% of my projects receive a minimum 4 coats of polyurethane( satin )and some up to 6 (painted or unpainted). Lightly sanding with a 1500 grit between each coat. Each coat is left to dry 1 day before applying the next. Once I’m satisfied with the number of coats I lightly sand the project with 1500 grit wet with bees wax wiping dry and polishing with a cheese cloth. The final result feels like glass to the touch. I’ve been using this process for over twenty years. Yes I know there are many other beautiful finishes but this is the one I prefer.
