How to Oil Can Finish a Golf Club

By Spencer Lanoue

Giving your raw wedges that gorgeous, deep, and slightly rustic oil can finish is one of the most satisfying customization projects a golfer can undertake. Far from being just about looks, this process connects you to a long tradition of golf club craftsmanship. This guide will walk you through everything you need to know, from the tools required to a detailed, step-by-step process for safely creating that beautiful, professional finish at home.

What is an Oil Can Finish?

An oil can finish isn't paint, nor is it a type of plating like chrome. It's a form of metal treatment called black oxide or heat tempering. The process involves heating a raw carbon steel club head to a specific temperature and then quickly cooling - or "quenching" - it in oil. This rapid cooling in an oxygen-deprived, carbon-rich environment (the oil) forces a stable layer of magnetite (Fe3O4) to form on the surface of the steel. This durable, oxidized layer is what creates the dark, often iridescent finish.

Unlike a thick chrome plating, the oil can finish is incredibly thin, which is why many players believe it preserves the raw steel's true feel. It offers moderate protection against rust Twithout creating a barrier between the ball and the metal. Over time, the finish will wear and evolve, particularly on the sole and face, developing a unique patina that many golfers find very appealing. It's a "living" finish that tells the story of your game.

Why Do Golfers Love the Oil Can Look?

Walk the range at any professional event, and you'll see plenty of players gaming wedges with dark, non-glare finishes. The oil can aesthetic is popular for several practical and personal reasons.

  • Aesthetics and Tradition: There's no denying it looks fantastic. The finish has a classic, Tour-van feel that evokes images of master craftsmen like Bob Vokey and Roger Cleveland hand-grinding wedges in their workshops. It’s a purposeful look that says you’re serious about your short game.
  • Reduced Glare: This is a big performance benefit. Bright, sunny days can create a distracting glare off a chrome wedge at address. A dark oil can finish absorbs sunlight, eliminating glare and helping your eyes focus on the ball. This can improve your concentration and confidence when standing over a shot.
  • Perceived Softer Feel: Oil can finishing can only be done on raw carbon steel wedges, not on stainless steel. Carbon steel is a softer material than the cast stainless steel used in many game-improvement clubs. Purists argue that because the oil can finish is a treatment rather than a plating, it allows you to feel the uninterrupted, soft feedback of the carbon steel at impact.
  • The DIY Connection: Creating your own oil can finish is a deeply rewarding project. It’s a chance to personalize your most important scoring clubs and build a deeper connection with your equipment. You aren't just buying your tools, you are making them your own.

Your Shopping List: Gathering the Right Tools and Materials

Before you start, make sure you have everything you need. Setting up properly is essential for getting great results and, most importantly, for staying safe. Most of these items are readily available at a local hardware store.

Safety First (Non-Negotiable)

You are working with an open flame and hot oil. Do not take shortcuts here.

  • Heavy-Duty Heat-Resistant Gloves: Welding gloves or similar are essential.
  • Safety Glasses: Protect your eyes from splashes of hot oil or sparks.
  • Fire Extinguisher: Keep a Class B (for flammable liquids like oil) fire extinguisher within arm's reach. Better to have it and not need it.
  • A Well-Ventilated Area: This project must be done outdoors. Working on a concrete patio or driveway away from flammable materials is perfect. The process creates a lot of smoke.

Equipment and Supplies

  • A Raw Carbon Steel Wedge: This process will NOT work on chrome-plated or stainless steel wedges. The club head must be made of raw carbon steel. A strong magnet will stick firmly to carbon steel, it will have a much weaker pull on most stainless steel formulations. If your wedge is already black, that is likely a black oxide finish that is perfect for this process. If it's chrome, it cannot be done without stripping the chrome first, which is a complex chemical process best left to professionals.
  • Acetone or a Strong Degreaser: To completely strip all oils from the club head before you begin.
  • A Metal bucket or Container: A deep, sturdy metal can, small metal bucket, or old metal saucepan works perfectly. It needs to be deep enough to fully submerge the entire club head in oil. Do not use plastic or glass.
  • Used Motor Oil: This is the classic choice for a dark, rich black or gun-metal blue finish. You will need about a quart. For a different look, some people use vegetable or canola oil, which tends to produce more bronze and brown hues.
  • A MAPP Gas or Propane Torch: A simple handheld torch is all you need. MAPP gas burns hotter than propane and will heat the club head faster, but either will work.
  • Clean Rags or Blue Shop Towels: For cleaning and wiping down the club.
  • Optional (for refinishing): If you are removing an old, rusted finish, you may need a Scotch-Brite pad, fine-grit sandpaper, or a rust remover product to get it down to the bare, raw steel.

The Step-by-Step Guide to Applying an Oil Can Finish

With yuur materials gathered and your workspace set up safely, you're ready for the exciting part. Follow these steps carefully, and do not rush the process.

Step 1: Prep the Club Head Meticulously

The quality of your finish is directly related to the quality of your prep. The club head must be surgically clean. Pour some acetone on a clean rag and wipe down the entire club head - the face, hosel, sole, toe, every single crevice. Then, do it again with a new clean part of the rag. Any lingering oil, residue from your hands, or dirt will prevent the finish from forming evenly and result in blotches. From this point on, handle the club with gloves to avoid getting finger oils on the clean surface.

Step 2: Set Up Your workstation

Place your metal can on a level, stable surface like the concrete floor. Pour the oil into the can. It should be deep enough to fully submerge the head and hosel. Put on your safety glasses and gloves. Have your torch in one hand, your wedge in the other, and have the can of oil close by and easily accessible. Before lighting the torch, mentally rehearse your next two moves: heating the head, then plunging it into the oil.

Step 3: Heating the Steel

Now, ignite your torch. Hold the golf club by the grip, well away from the torch flame. Begin to heat the club head evenly and constantly. Keep the flame moving - don't let it sit in one spot for too long, as this will create hot spots and an uneven finish. Move the flame back and forth across the face, over the back, along the sole and topline.

You're about to witness the beauty of tempering steel. Pay close attention to the colors as the steel heats up. You will see a progression like this:

  1. Silver -> Light Gold/Straw (~400°F)
  2. Straw -> Brown/Bronze (~450°F)
  3. Bronze -> Deep Purple (~500°F)
  4. Purple -> Dark Blue (~550-600°F)

The classic, desirable "oil can" look comes from the heat range that produces those stunning blues and purples. Once you see these deep colors start to fill the head, you're ready for the next step. Ddon’t overheat it! If it starts to glow orange or red, you’ve gone way too far. This can soften the steel and negatively impact the club's feel and durability.

Step 4: The Quench

As soon as you achieve that beautiful blue/purple hue across the head, turn off your torch and immediately - but smoothly - plunge the entire clubhead straight into the container of oil. Be ready for a good amount of smoke and a "poof" or "whoosh" sound as the hot metal displaces the air and makes contact with the oil. This is completely normal but demonstrates why an open, clear workspace is so important.

Hold the club submerged in the oil for at least 30-60 seconds. You'll hear the sizzle go down as it cools. This is the moment the finish is created.

Step 5: The Reveal and Cleanup

Using your gloved hand, carefully lift the club out of the oil. It will be dripping, but you can immediately start wiping away the excess oil with a clean rag. Underneath that grimy layer of motor oil is your incredible new finish. The head will still be warm, so continue to handle it with gloves. Give it a thorough but gentle wipe-down to remove all the surface oil, and then let it sit to cool down completely to room temperature before handling without gloves.

Aftercare and Maintaining Your New Finish

Congratulations! You just customized your club like a Tour Pro. Now, how do you take care of it? Remember, this is a living finish built on carbon steel. It needs a little care.

  • The Wear is Part of the Charm: The finish will wear over time, especially on the face and sole where it makes contact with the ball and the turf. This is normal and expected. many golfers love this "used" character it develops.
  • Fight Off Rust: It is still carbon steel, and leaving it wet will cause rust. After your round, especially on a wet day or on a heavily watered course, just take 30 seconds to wipe the club head down with a dry towel.
  • Use a Silicone CLoth: For added protection, you can wipe it down with a silicone-impregnated cloth (often sold for gun care). This leaves a thin, protective barrier that repels water. A tiny bit of WD-40 or gun oil on a rag also works wonders.

Final Thoughts

Creating a custom oil can finish on your raw carbon steel wedges is a rewarding project that marries a bit of workshop know-how with your own personal style. By carefully prepping, heating, and quenching your club, you can achieve that sought-after Tour-inspired aesthetic right in your own garage and forge a stronger connection with your scoring clubs.
