i have the spary can varnish but its still not as smooth as i want it, maybe im just expecting to much for a homemade longboard im not sure is there a certain varnish that i should be using and is buffing something i should be doing or is that just over the top or useless.
I just saw this post and my reply has nothing to do with finish but I want to cut this statement off at the pass, as it were.
adopt the mindset that you can't get something as nice as commercial grade products just because it's handmade.[/u]
You can get your end results to be as nice and with enough effort and research even better that what you find in the stores. Big companies are likely using the exact same methods you are but can afford to automate the processes. A lot of these companies are also beholden to the bottom line which means that cutting corners and quality assurance can become big issues.
As for your finish, listen to AM Wood, he posted great advice. The secret to a nice finish is elbow grease
