Finished case prep by grinding/sanding/Scotchbrite outside of engine case. Wash with mineral spirits followed by a wash with soap & water. Checks for loose casting flashing. Taped and painted cylinders and engine crankcase with ceramic engine paint. Prepare crankcase for assembly, mount port side case to engine stand. Assemble bottom end. Used Curil K2 rather than the recommended Permatex Aviation sealant for case haves, obtained good sealant squeeze-out around case perimeter.
