Just cut out the sheer panels on this boat. However I messed up on one of the scarfs in that the carf was sanded too thin amd broke away leaving a small deppression on the panel. What is the easiest/best method of filling the depression so I wont see the repair on the finished painted hull?
Could you get some thickened epoxy in there? It will fill the void and tie it all together. If anything is above the surface when it cures, use a scraper instead of sanding... or at least minimize sanding. Seeing as how you will be painting, it will be invisible when it's all done.
