Hi Leo. Yes, the time has come to stop filling. I doubt those small cracks are going to give you a problem. Filling after the boat is sanded can have other repercussions anyway: residual resin can soak into the abraded wood fibers and cause discoloration (splotches) under your fiberglass.

Best of luck,
