Harbor Freight Spray Guns Reviewed

Then there’s that kind of panic, the one where you need something to go on smoothly and don’t own a spray gun. You’ve got the paint all mixed up, the surface is prepped, and time are running out. The local paint store has what you want, but it’s not in the project budget.

And then you see the aisle at Harbor Freight and it appears to be a lifeline. Now we get to the real question: Can you buy a gun there? No, the question is will it make it through the first coat without spraying you with tiny bits of dissapointment?

Why Budget Spray Guns Have a Reputation

But know what? Harbor Freight gets a reputation for selling something that works once or twice and then stop working. And they’ve earned some of that rep.

They has also made that reputation bigger than it needs to be. Finishing work means more on the line. A failing drill ceases to spin.

A failing spray gun fouls up a door, a cabinet, or a chair. You will spend hours sanding. You’re not looking for “get the job done.” You’re looking for a consistant atomizer.

You need one that holds pressure. The brands they have will range from terrible to surprisingly competent for price. Don’t think of them all as a monolith.

Some will be better built then others. There are a lot of private label versions of budget sprayers on the market. Often, these guns is based off older models made by big-name companies that was later discontinued.

But that is the key; they’re brothers and sisters to some solid tools. If you understand where to look, you’ll be able to weed out the plastic junk and land on some steel bodied guns that work as intended. You just need to dig a little deeper into the pile and be willing to try before trusting.

We want to sift through the trash and find the treasure without wasting your hard earned cash on something that’s gonna quit halfway through the job. So let’s look at the basics: the traditional gravity feed HVLP set-up. Here are your main tools for the budget class.

Choosing the Right Spray Gun Type

You’ll find Mac Tools and other names here. Mac Tools have their gun and it gets mentioned as the best bang for the buck in the room. It has a good trigger mechanism and a stainless steel fluid path.

It is not a competition winner against a brand new pro model at $200, but it can put on a coat of enamel or lacquer that looks just fine from three feet away. Key is to clean right after using. Seals cheap out if left wet with dried product sitting in there.

Treat her right and she last. The other type is the siphon feed gun. They pull paint from a container below the nozzle.

They are cheaper and easier to maintain, but they has issues with viscosity. They stutter on thick catalyzed automotive clear. They work best with lacquers, shellacs, and lightly thinned enamels.

Common siphon feed models here are the General. They is solid for an occasional user, but lack the precision of gravity feed. You don’t get control over volume of fluid and fan shape.

That’s the compromise for lower cost and ease of care. Don’t expect perfection here. Now, this is really where the rubber meets the road, durability.

Durability and Material Quality Check

To drive down cost on many of these guns, they uses plastic internal parts. There is no problem there with dilute primers and water based stains. But solvent?

Nope. Over time, those chemicals will actualy dissolve cheaper plastics and cause erratic spray patterns as well as leaks. One place to check when you shop is the needle and tip assembly that holds the paint fluid.

Is it stainless steel or does it look like brass? You’re good. Is it plastic?

Well, I wouldn’t count on it lasting very long. This isn’t some conspiracy. It’s material science 101.

Solvents are killers of polymers. Metals live. But does it cleans?

That’s really where we find out. I’ve seen guys who spend a few bucks on a cheap gun. They buy a cheap gun and lose interest when they realize how hard it is to unclog the tip.

The gun spray poorly. A gun that sprays poorly creates a bad finish. And the kits at Harbor Freight are interchangeable.

That’s a huge plus. You can drop in a different size. No big deal.

With an expensive gun, you have to replace the whole assembly. So, the way the cheaper versions are built in parts means it’s more forgiving if you do something wrong. You might make a mistake, but don’t quit.

Keep going. That’s the main point. It is not about the upfront price, but the price per use.

Maintenance and Cleaning Tips

These are great tools to have around but you need to scale your expectations back accordingly. Don’t take a Harbor Freight spray gun and spray a high gloss automotive clear coat on a show car. You’ll hate yourself.

Take it out and use it to prime a wall, stain a fence, or finish a piece of furnitures that will go behind your sofa. Then it serves a purpose. You’ve saved money not having to rent something.

You sprayed a nice consistant coat. That’s what the gun was made for. And you know when it’s time to draw the line between OK and just enough.

Change the tip when it wears. Clean it well. Don’t ask it to do more than it was designed to do.

Realistic Expectations for Budget Tools

You’d be surprised at the amount of good work you can accomplish with a good budget tool.
