Photos? Is it porcelain enamel?

Hi, Peanut!

It's um...whatever was used on '50s cast iron sinks. I guess enamel?

Here's the overflow. I think the white stuff is Comet. Kids are terrible at cleaning...

My husband epoxied our 2 bathtubs and one old bathroom sink. Because he did it himself there are some brushmarks, But I would think if your sink is white, you might be able to just touch up those trouble areas. The key is preparation.

A friend of mine who had a "professional" with a sprayer do it had a disaster. the woman didn't do any prep and the sink started to peel within weeks. While it lasted there were no brushmarks tho.

Good luck,
Kathy

Thanks, Kathy. It's actually pinkish. Not the cool pink, either. But it seems like most of the rusting is inside where it won't show--as long as it slows the rusting it's worth checking out.

It looks like I'll have to get in there and remove the drain and see just how far it's gone.

I have an original cast iron sink that has an overflow compartment that is rusted. My problem is that i had the sink professionally sprayed by a reputable comanyvin Buffalo NY. shortly after I noticed rust around the overflow holes. That led me to looking beniethvthe sink where I found that there is a small pocket where the water ends up going and it is rusted in there I assume from the standing water what can I do to get the rust out? Maybe pour coke in there? they say it desolves rust. Please any suggestions?

I AVE THE SAME SINK. HOW DOES ONE GET THE RUS OUT OF THE OVERFLOW?

I have the same problem. Professionally painted - OVER THE RUST - now peeling off and exposing rust. How do I remove the rust and stop it from spreading - because rust "grows"?
