Before using spray paint, it's a good idea to apply a coat of paint primer. Rust-Oleum 2X Ultra Cover Spray Primer seals bare wood so the paint doesn't absorb too quickly into the porous surface. It also leads to a smoother and longer-lasting spray paint finish.
A coat of primer before paint helps ensure great results.
Keep in mind that if you don't use primer, the paint job may not last as long and could be more prone to damage over time.
Skipping primer can result in poor paint adhesion, leading to peeling, flaking, and chipping over time. This affects the appearance of the painted metal and reduces its durability and lifespan. The paint may only stick appropriately with primer, especially on smooth, shiny surfaces like aluminum or stainless steel.
Paint alone does not adhere as well to rust and when it does stick, rust stains can bleed through the paint coat and discolor it. Typically for rust, you do not want to use a latex (water based) paint because it may cause the metal to rust more and will bleed through and stain the paint.

Condition of the Surface: If the metal surface is new, clean, and free from rust and corrosion, it may not require a primer. However, if the surface is rusted, pitted, or has any imperfections, a primer is necessary to create a smooth surface for the paint.
Above all else, self-priming paint is designed to eliminate the need for primer. It is typically thicker than average paint, with a higher concentration of solids to help cover blemishes, leave a more robust finish and ultimately make the process quicker and easier.
Most acrylic and latex paints will not stick to oil-painted surfaces without primer. So before you begin, it's important to check whether the existing paint is oil-based or water-based. In older homes, the wood trim and walls were usually painted with oil-based paints, so it's important to know what's on your walls.

Applying vinegar to rust dissolves the oxide and leaves behind a water-soluble salt that you can remove easily. It is called neutralisation, and this reaction happens between rust and acetic acid, which is why cleaning vinegar helps remove iron oxides from household surfaces and objects.
Acrylic latex paint is best paired with a water-based latex iron oxide primer when painting over rust. It is easy to apply and one of the paints known to be less messy. Amongst latex paints, acrylic is regarded as the best and highest quality of the bunch.
