I am wary of Crazy Glue as I have read that it is more likely to promote lead bloom (a disease so terrifying it must be whispered) than some other glues. I'm currently using an ph neutral white glue (which doesn't have much strength) in conjuction with pinning for that kind of repair, although even that may also prove to be folly in the long run. I have only the barest knowledge of chemistry, but I think that almost all glues (all that I've run into) have some acid content (I wonder if that plays a part in the bonding), and the acid tends to cause the oxidation that results in lead bloom. I read on a site concerned with preserving the lead fittings on model boats that silver solder is the only real long term fix. The war against lead bloom is truly an intergenerational struggle, and in the end, the laws of physics will have their say, as entropy sets in. As for resale value, someday, my daughter will be cursing me for repainting my Britains and decreasing their resale value, so I would recommend doing whatever seems the most fun!- Emily
