Replying to Durability of repainted skis

If any of you have repainted your skis i take it you know how quick they can get scratched. I'm in the middle of repainting my skis and i was thinking about what could be used as a top sheet to make the design last longer. Have any of you ever tried using wooden floor varnish? Its really strong against scratches and wear and tear for obvious reasons. The only draw back i can think of is it has to be painted on so will give a slight painted effect instead of the smooth finish you get from spraying.
