is used 16 mm black mdf for a bartop project . i clear coated every part of it with acryl paint . the advantage is u dont need much painting nor t molding . the appearance isnt 120 % ultradark black , coz " black " mdf usually has some brighter i would call em microscopic dropouts. colored mdf is available in red , green , yellow, blue and more. i advise clear coating with professionell car paint. unpainted mdf looks more like grey than black.
for bartop or cocktail purpose its no bad choice at all , but a fullsizer would be a little 2 expensive.
