assessing the leaky bolt

I have been reviewing other Matilda blogs in light of events. Fortunately, mine is NOT a "tail-heavy" keel bulb, and shows no sign of the typical serious deteriorations discussed. Unfortunately I find no mention of my particular problem on the blogs. Upon inspection, I'm pretty confident new sealant around the "limit/pivot" bolt head and nut will solve my leak (and I think I can test it without relaunching).
