It is important that you are able to find the right paint for your metal storm security door. The paint that you choose will have to be one that you know is not going to chip easily or fade. Durable paint is necessary.
Acrylic Spray Paint
If you were to use an acrylic spray paint then you would run much less of a risk of it chipping or peeling later down the road. This type of paint can easily withstand the harsh weather and conditions that this door will have to endure.
Latex paint also works very well when it comes to being durable and long lasting for your metal door. This is definitely one to consider.
How to Choose
Make sure that you go over the cost and what you expect your metal door to have to go through. If it has to weather harsh conditions, make sure you go for something durable.
It is never a good idea to use a paint brush whenever you are painting a metal door. This will leave lines. Typically, a foam roller or a foam brush will allow you to be able to get the job done the best.
