Only certain paints will protect steel.
Paint is required to provide a finished look and protection to steel, but only certain types of paint are suitable for steel. Latex paint and oil-based paint are most commonly used.
Latex Paint vs. Oil Paint
Latex paint can be applied over older oil paint, but oil paints may form ugly cracks over time when applied over latex paint.
Best Primer to Use on Steel
Before you paint bare steel you will want to apply a steel primer; this coating deals with any preexisting rust problems and prevents future rust problems. Just make sure that the primer states that it prevents rust.
Best Paint to Use On Steel
A high quality acrylic latex paint is worth investing in; opt for 100 percent acrylic paints over cheap paints. Acrylic latex paints are better options than matte paints as they are easy to clean, last longer even after being exposed to extreme weather conditions, and can make maintenance a lot easier.
Advantages of Oil Spray Cans
Oil paints in spray cans are convenient to use as they don't require mixing or much technique and you are left with a consistent looking paint job. Oil paints also hold up well against humidity and extreme temperatures.
Things to Remember
Dark color paints tend to fade sooner. Select paints suitable for the atmosphere they will be in. If you want to keep the natural look of the steel, go with a metal protectant which goes on clear and dries clear. This can also be used as a primer.
