Look at Snowolf's video on how to wax a snowboard. Look towards the end of the video. He shows you a great clear view of it to make you appreciate what a waxed board looks like.
It's only after I watched his video then that I realized I had done the diy job right. Prior to watching his video, I actually wondered if I properly waxed my board. It's a great comprehensive video.
Watch at at 9:15 and you know what I mean.
