Q. How do you refinish a galvanized old bathtub and do you put any thing on the inside and what if you have rust inside, what can I do to fix it. I do want to use the bathtub. Help, please.

A. Hi Deb. If it's rusted inside it's probably best to paint the inside. Scrub off whatever rust and scum you can with a scrub brush and Spic 'n Span [affil link] or anything like that, then a primer designed for galvanized metal -->
then whatever color paint you want.

RFQ: Hello,

I have an antique zinc bathtub that has holes in the bottom of it. I am looking for anyone who can lead me in the right direction to get it repaired. I live in California but am willing to send it anywhere and pick it up.

Any help would greatly be appreciated.

Q. We too have an old galvanized bathtub on legs. It has peeling white paint on it. Thought an auto body repair shop might strip it and repaint it...might be very cool.
Does anyone know the era of these tubs?
Thanks,

Q. I hope you can help me from making a mistake. I am in the process of restoring my grandmother's farm house (built in 1868) and have questions and need answers. I would like to install an antique cowboy galvanized bathtub (with an oak rim) which is a little rusted. How do I arrest the rust with out discoloring the galvanized metal? I've read "lemon" will discolor the metal. Do I use Naval Jelly? I have also found out that the tub will continue to put off (on the surface) a dusty powder to the touch, can I eliminate this discharge? the original tub(s) were left with the galvanized metal exposed. Would it be a mistake to paint the surface, and what kind of primer and paint do I use? I thought of using "auto" paint, applied by a auto body shop, ya or na? My last question is if the seams leak how do I repair this problem and with what materials?

Looking forward to hear your advise.

A. Try 5-10% ammonium citrate solution (50-100 gm citric acid/1 lit water+add some ammonia+pH must be 3,5 for rusted spots, or 7 for galvanized surface).Solution for iron must be used on iron and second solution must be used on galvanized parts.Instead that you can use WD 40 or Balistol (oil based rust removers)+lot of elbow grease.Hope it helps and good luck!

A. If you can separate the tub from any other components (wooden trim etc), then I suggest you get it re-galvanized.
This will arrest the rust, and likely seal any leaky seams (unless gross gaps), and you'll end up with a newly galvanized finish. If you want to accelerate the aging after this (it'll be shiny zinc initially), there are ways to do that explained elsewhere on this forum.

A. Ms. Betsy

I agree with Geoff.

There are no galvanizers in South Dakota. There are several in central and eastern Nebraska including: Hastings, Atkinson, West Point, McCook, and Valley.

RFQ: Is there anyone near the Kansas City, MO area that can repair an antique 1800's galvanized cowboy bathtub? The fixture is newer, but the drain is original. There is a large 1'x1' fiberglassed patch job on the bottom and in order to cover up the rust and patch job they painted the outside of the tub and glazed the inside. The cast iron feet, drain, and oak trim are in excellent condition.

RFQ: Wondering if you found anyone in the KC area as I just acquired one of these tubs that needs some attention as well.

Q. I've got an old metal baby bathtub with white enamel that is chipped in various places. What is the best way to resurface this so it will be durable and long lasting?

A. Hi Teresa. The original finish was probably vitreous enamel (porcelain enamel) which is essentially melted glass rather than paint, and something a consumer won't be able to do. Unless you can afford a professional restoration, appliance enamel is probably the best you can do.
