That's not that deep. I was worried they were deeper.
I would just let them dry out for a couple reasons. One, the air will heal them up hard, and any filler or silicone's added will get you disqualified at your weigh-off.
Keep them dry and they'll be hard and healed in a few days. I remove the ooze and spray with peroxide to kill any funky stuff, then wipe dry after a minute or two and let the air and sun hit it.
