Have you ever wondered what is the most durable spray paint out there? It turns out there are a few good sprays to consider. Their applicability around the house is wide.

You can enamel spray paint the following

  • A bike
  • Aluminum surfaces
  • A car

4 things you need to know when choosing the most durable spray paint

There are a few things to know even if you buy the best spray paint that lasts. Ideally, you won’t build up false expectations.

  1. It costs more than regular spray paint

Spray paint such as enamel spray paint that is very tough typically costs a bit more. You might even end up paying more than $20 per spray. This might only be sufficient to cover an area of up to 14 square feet.

  1. It’s typically oil-based (or epoxy-based)

Even the most durable paint for metal is oil-based (red more about oil-based paints in our Is Rustoleum Oil-Based post). This means you will need to consider where you paint as clean up can be considerably more difficult than with water-based paint sprayers or acrylic paint sprayers.

  1. The toughest spray paint for metal takes longer to dry

  • UV-resistance

UV-resistance is a must if you plant to spray objects that are outdoors or that are made to be used outdoors (i.e. bikes, kids’ playground). In fact, constant direct sunlight exposure is one of the main reasons paint chips in the first place.
