A ships hull is not entirely rust proof
It is usually protected with paint
Epoxy would work best
Application of Fish Oil.
They are exposed to the weather and are not made of a rust-proof metal.
Most ships hulls are iron based, so the issue of oxidation is ever present. The application of magnesium strips to the underside of the ships has proven effective in preventing rapid corrosion.
They should be made from rust proof galvinzed steel.
Something that is rust resistant will not rust easily; minor exposure to water will not cause it to rust. Something that is rust proof will not rust.
They spend a lot of time at sea... Salt water is corrosive - any imperfection in the ship's paint allows the salt water to penetrate the hull. Water and metal creates rust !
Fiberglass has a higher ratio of strength to weight than steel does, and it is also completely rust proof, unlike steel.
Depending on the company that made the outside furniture. However these furniture is really expensive, and they made rust due to certain elements.
Usually iron covered in enamel or chrome to rust-proof it.
Electronic rust proofing works, by the fact that iron(steel) ionises to Fe^3+ (The Iron(III) ion). So if you have a substance that ionises more readily than iron, it will 'flood' the system with electrons, so that iron cannot lose electrons as there are too many already in the system. Since iron cannot lose electrons it does NOT oxidise (rust). NB: Ships have Gauss Blocks applied to them in a Graving(Dry) Dock. The Gaus Blocks are made of magnesium, which ionises more readily than Iron(steel). Hence a ships underwater hull is protected from rusting.
stainless
You can if you want to
The answer is... Yes! certain types of paint make them rustproof.
