Good for you! I've had good experience with Bobby. As the for Loctite 518, I could see some red around the edges of the carb block/crankcase seal when I got the one engine back from Cactus, and when I resealed my other engine myself, I put a thin coating of the 518 on one surface, and when I tightened it down it squished out of the joint, leaving the same red line as the other engine. So, I would have thought that if your engine had received the same treatment, it would have had the same red sealant around the joint. Please keep us informed as to your progress.
