Best Overall: Rustoleum Automotive Metal Primer

Rustoleum Automotive Metal Primer
Buy on Amazon

Rustoleum has been making good-quality primer for years, thanks to a combination of clever design and high-end materials. It provides rust resistant base coat for cars, trucks, and other vehicles. It can be used on wood, metal and fiberglass. It provides rust resistance while the 2 in 1 formula fills surface imperfections and primes the surface. It is a great way to remove the 3D printer lines on larger models.

One coat of this plus a good sanding is enough to get rid of the lines completely, and it's a lot easier than an epoxy-based one like XTC3D. It will look very thick after the first coat but that will evaporate and thin out so you will need a few coats.

Why We Like This:
  • Perfect to help fill in little imperfections
  • Really helps smooth out minor level changes when doing auto body work
  • You will get cracking, bubbling, and all
  • Great for primer coating funky metal surfaces

Best For Aluminum patio furniture: SEM etch Primer

SEM etch Primer
Buy on Amazon

The sem etch primer is specially designed for your daily usage and has all useful features. It sticks like glue to any clean surface and is great as a primer before paint or just by itself. It works well for refinishing alloy wheels. It has bonded to the aluminum, unlike the dupli-color. It will tell you the temperature range.

This is made for clean raw steel, wire brushed or sandblasted. The primer works, but the spray pattern + consistency makes it much easier to use. It goes on smoothly, dries quickly, and produces a nice even finish.

Why We Like This:
  • Good brand reputation
  • Lot of satisfied buyers

Best For vehicle: Eastwood Automotive Metal Primer

Eastwood Automotive Metal Primer
Buy on Amazon

This easy-to-use aerosol etches and primes bare, rust-free metal in one step. It is easy to use for aerosol cans or economical quarts and gallons. The etching primer uses an aggressive solvent system to assure excellent adhesion to clean, rust. It is also a single-stage formula that requires no catalyst, making it even easier to use.

The adhesion is much better than regular primer alone under the finish coat. It is easy to use for spot repairs and bonds better than other aerosol primers while a gallon can has more value for big projects. It is good primer for a truck restoration project. It is easy to use for chassis and undercarriages, you might even simply put a clear coat or seam sealer over it and let the black color shine through.

Why We Like This:
  • Enhances adhesion and durability of most non-epoxy top coats
  • Perfect for painting knobs, hindges, etc
  • Withstands up to 170 degrees f, made in usa
  • Adheres to steel, stainless, aluminum and chrome

Best For Bare Metal: SEM Automotive Metal Primer

SEM Automotive Metal Primer

If you attempt to apply with a brush outside in the sun, it almost dries as you stroke it on. It is easy to apply using a hvlp gun. This is ready to go out of the can and works perfectly for metal where you need a self etching primer. It is nicer to look at brown rust. This paint dries REALLY FAST. This is the primer to use if you are painting cast aluminum.

Why We Like This:
  • Whips through corrosion and rust, preps bare steel for painting
  • Good investment for long term
