I did a battery post leak repair and its been about six months and no sign of leaking. I gave a good cleaning around the base of both posts even though it was only one that was leaking. I had a small bottle of touch up paint for one of my cars. I used the brush and painted around the post a few times maybe 3 or 4 coats of paint. I can't say if the paint seeps into the leak area or just seals it at the surface but it seems to have worked for months already
