Holey utility zinc sink!

Q. I have an OLD zinc utility sink with a corroded hole. The bottom of the sink is also rusted. Can repairs be made? I would rather not replace it with a polypropylene tub but keep it for the history. The building is 100 years old - the sink must be close to that!

A. Hi Sharon.

Epoxy is underrated; I used JB Weld ⇦ on eBay or Amazon [affil link] on a burst outdoor brass shoer valve and it lasted for years. If it's a pinhole, I'd fill it with the epoxy. If it's larger, I'd cut a small piece of galvanized sheet metal and use epoxy to glue it over the hole.

After that, apply rust converter ⇦ on eBay or Amazon [affil link] and then zinc rich paint (sometimes called cold galvanizing paint to the inside. Good luck.
