Most paints work well on metal with the right application process, and you should have good results with most high-quality varieties, including both water-based acrylic paints (also called latex paints) and oil-based paints (also called solvent-based paints). Look for a paint that is rust- and fade-resistant, and that is suitable for use on an exterior door.
Pros often use oil-based paints for metal surfaces, since they’re the most durable for the job. However, these types of paint are more toxic than their water-based counterparts, and require both a longer drying time and a tougher clean-up process.
It’s up to you to decide what you’re up for and what’s in your skill set as a DIYer, but here’s a breakdown of the pros and cons of both types to help you choose.
