Which paint is more rust resistant, enamel or acrylic?

i just wanted to know so that i can form a hypothesis.please help me. i need an answer as soon as possible.Which paint is more rust resistant, enamel or acrylic?
For rust to form on metal, it must have moisture and air. Enamel paints seal (if done correctly) the entire surface, not allowing air to get to the metal. The secret of using enamel is to prep the metal first, prime it and then several coats of enamel paint. It wont be bulletproof, but it wont rust.Which paint is more rust resistant, enamel or acrylic?
Except for flat finishes, all paint forms an enamel when it dries. So if you're painting over rust, you don't want to use just any enamel paint. The best choice is oil-based paint, especially a rust-resistant product like rustoleum. Oil-based paint will also bond to metal without peeling, but acrylic paint will usually peel from metal surfaces. The drawback is that oil-based paint takes longer to dry, smells bad, and requires paint thinner or turpentine for clean up.





P.S. Regardless of which paint you use, you should treat existing rust with a wire brush or a rust reformer spray before painting over it.
Neither of them are subject to rust. Iron must be present, in some way, for rust to form.
Enamel of course.
Enamel, but then you have Arcylic Enamel


Oil Based Enamel is the toughest and most rigid.
