Adding tack fillets and, after removing the side panel drywall screws, a thicker chine fillet is a messy and hard job. Tough on the low back. I can't wait until I get to do the work inside and underneath the hatches.
It looks like the thixotropic properties of the Cabosil in the resin/filler fillet mix are not 100%. Some sag there but nothing several dozen hours of sanding won't fix. Or maybe just move on to the extra glass layers. It is, after all, the inside of the boat. Covered mostly by a deck.
