I was just having a gander at your charming resin infusion starter kit, and was wondering if it would fit my needs. I've only ever done wet hand layups in the past, so jumping straight into resin infusion vacuum bagging is a pretty big step for me. 

We know your board is actually closed. But the fact remains that it most likely won't survive the pressure/vacuum. If there is only one small crack or hole you will suck lots of infusion resin inside. And such a crack has to be expected once you bag it and put it under vacuum.
