hey i too build longboards, and there are way, way to many ways to doo good graphics. my suggestion is to go to www.silverfishlongboarding.com
its like the NS of longboarding. in the forums, theres a forum called board building. there you will find all yout answeres.
buts some personal suggestions of mine:
fabric: cotton fabric prints can easily be epoxied to the board for a sweet, easy graphic
spray paint and stencils, if done right, they can look just like screen printed stuff.
rice paper prints: you can print graphics on a special paper like rice paper, and then wet it out with epoxy and laminate it to your deck.
whatever you do, ge some type of strong clear coat, Urathane is Really good, but takes a while to dry, polyurathane resin, or polyurathane clear coat. just make shure its not crap. this is where you spend extra to get the good stuff. id reccomend urathane. oh, and i dont know what kinda ridding you do, but if its mellow surf style skatting, and nothing too aggressive, a Silicone grip job is a good idea. not only is it 100% clear, but it really dampens the ride, and gives pretty damn good grip (as long as it isnt wet) plus it last a long time. hit me up if you have any other longboard questions, id love to help!
i looked on google but all i could find was 3D Animation porn-sxmarty6
