Can you paint galvanized buckets?
The best DIY method to repair and extend the life of galvanized buckets is to paint them.

This means that steel has to be chemically pretreated before it can be hot-dip galvanised, with rust, mill scale, thin greasy layers, and various types of oil being removed.
Will a galvanized bucket rust?
Metal buckets can last for years, but some are prone to rust. Galvanized steel buckets aren't likely to rust on their own, but any action that exposes the inner layers of metal can increase the risk of rust. Drilling drainage holes, for example, can lead to rust in the bottom of the bucket.
Can you paint over rusted galvanized metal?
Removing rust is an important first step because if the rust is not removed it continues to spread creating rust-holes that are difficult and expensive to repair. Once all the rust is gone from the galvanized metal, then you can paint it.
How do you fix a hole in a bucket?

Factors that rust and corrode galvanized steel: Relative humidity above 60% Sodium chloride (salt) in water or air.
What does vinegar do to galvanized steel?
White vinegar is effective and non-toxic which is much safer to use rather than an industrial solvent. All you need to do is apply the vinegar on a clean rag and then simply wipe down the galvanized surface. The great thing about vinegar is that it has an acidity that will react with the metal, promoting pain adhesion.
Does vinegar remove galvanization?
Weak acids are cheap and pretty safe. The recommended acids to remove galvanized coatings are acetic acid and citric acid. Acetic is the acid in vinegar, and citric is the acid in lemons. These acids are pretty safe for occasional usage since they have low corrosion power.
What to use to clean galvanized steel?
Use these items: emery cloth, a wire brush, sandblasting , etc. Cleaning galvanized steel surfaces is often done with a stainless steel wire brush. To ensure a smooth surface result, surface preparation should extend into the surrounding undamaged galvanized coating. Breaking the oxide layer by agitation is an important key to successful galvanizing ...
How to spread solder?
A stainless steel brush works well to spread the solder and ensure it is adhering. If additional layers are needed, continue to drag the rod over the area. Bring back the heat only to keep the surface, not the rod, hot enough to push the solder around to where you want it. ...

Clean surfaces in according with the requirements of SSPC SP10 (near-white). Where circumstances do not allow blast or power tool cleaning to be used, then hand tools may be used.
Why is galvanized steel rusty?
Galvanized metal is coated with a layer of zinc to protect the iron or steel underneath. If the item is exposed to continually wet conditions, the zinc develops a film known as white rust. Left untreated, white rust corrodes the zinc, and the metal underneath begins to rust, exhibiting the more traditional brownish-red color.
How to remove rust from metal?

What to use to repair a galvanized tank?
For larger leaks in open galvanized stock tanks, either a boiler repair plug or a nut and bolt with two rubber washers and two metal washers can be used. If a heavy water tank must be moved or lifted to repair a leak, have one or more helpers hold it securely to prevent possible injury from a falling or rolling tank.
Can galvanized tanks leak?
The tanks are covered in a coating of zinc, which protects the underlying metal from rust and corrosion. Over time, though, galvanized tanks can still develop leaks. Rather than discarding a leaking galvanized tank, fix small holes easily and inexpensively using simple tools and items from the hardware store. Advertisement.
Step 2: Structural Fix
Because the plastic has lost its strength, it now needs to be reinforced. Find a piece of scrap plywood around the garage, or go to a home store and buy one. The only requirements to keep in mind is that it must be as wide as the bucket is at it's widest point. I recommend at least 1/2" thick plywood, but 3/4" will work too.
Step 3: Cut It Out
I used a band saw to cut out the shape of the circle, but you can also use a jig saw or hand saw as well. Because the bottom of the bucket is curved, it's a good idea to trim off the bottom edge of the wooden circle at a 45 degree angle. This will allow it to seat snuggly in the bucket.
Step 4
Sand both sides of the wooden disc to make sure it's smooth and there are no sharp bits sticking up. You should also sand the sides for the same reason. Once smooth, choose which side is the bottom and apply glue all over.
Step 5: Flip It
Find a smaller diameter object, like a trash can to use as a brace. Flip the bucket over on top of the can so it will prevent the wooden disc from falling out and allow you to apply pressure from the opposite side.
Step 6: Screw the Bottom
Find screws that are shorter than the thickness of the plywood you used. This is important to prevent them from poking through into the bottom of the inside of the bucket. Find a drill bit that is smaller in diameter than the screws (so the threads have something to grab on to) and drill holes around all the cracked parts of the bottom.
Step 7: Secure the Sides
Now use longer screw for the sides. Drill holes all the way around the bucket, into the sides of the plywood disc. Space them out around every 3 inches. Screw in all your screws to give the bucket added strength from the unbroken sidewalls.
Step 8: You're Done!
You can now fill up the bucket with whatever you want! I needed it for wood scraps in the shop. The wood bottom actually makes it stronger than it was brand new, so it will give you plenty more years of service.
What type of paint should I use on rusted metal?
I'd recommend any enamel alkyd type paint specifically for exterior metal.
