I think that Chris meant that you could probably skip using the infusion mesh (flow media) altogether, being that the part is so small. This would give you a very slow infusion that would allow the resin to wet-out the fabric more completely and shouldn't pose any problems if you're using a slow hardener, but it should still infuse in reasonable time on such a small panel
It seems a bit counter-intuitive, but you would likely find things work more smoothly on a slightly bigger panel, as you wouldn't need to worry so much about controlling the resin flow. Infusing small and relatively thick laminates requires more careful planning than something closer to the size of part you'll likely be looking to make in the future
