Building the Tamiya Porsche 935 is a rewarding experience, but adding photoetch parts takes your model to the next level. These precision-etched metal details provide realism that plastic alone cannot achieve. Whether you are a seasoned modeler or just starting out, understanding what photoetch parts are available and how to use them effectively can transform your build.

Why Photoetch Parts Matter for the Tamiya Porsche 935
Photoetch parts are thin metal pieces cut with high precision using a chemical etching process. They replicate fine details like grilles, emblems, seat belts, brake discs, and dashboard panels. For a race car like the Porsche 935, which features intricate air vents, louvres, and sponsor decals, photoetch parts add depth and accuracy that plastic kit parts often lack.
The Tamiya Porsche 935 kit is already well-engineered, but the stock plastic parts can appear thick or lack crisp edges. Photoetch replacements are thinner, allowing for more scale-correct proportions. Additionally, metal parts can be painted or left bare for a realistic metallic finish, enhancing contrast with the body color.
Key Photoetch Parts for the Porsche 935
Several photoetch sets are designed specifically for the Tamiya Porsche 935. Here are the most common components you will encounter:
Radiator and Brake Duct Grilles
The front radiator grille and rear brake ducts are prominent on the 935. Plastic grilles are often solid or lack the open mesh look. Photoetch versions provide fine mesh or slotted openings that allow you to see through to the radiator behind. Look for sets that include the correct pattern—some replicate the original car’s horizontal or vertical slats.
Dashboard and Instrument Panels
The 935’s interior is sparse but detailed. Photoetch dashboard overlays include raised bezels for gauges, switches, and warning lights. These parts can be painted and then dry-brushed to highlight the edges, making the instruments pop without decals.
Seat Belt Hardware
Real racing harnesses are metal buckles and adjustments. Photoetch seat belt sets provide realistic buckles, adjusters, and even fabric belts (though some modelers use fabric or tape). The metal parts are far superior to the soft plastic or decal versions in the kit.
Emblems and Badges
The Porsche crest, “Porsche” script, and “935” badges are often provided as decals or thick plastic. Photoetch emblems are thin, crisp, and can be painted with a fine brush. They adhere better and look more like the real car’s metal badges.
Brake Discs and Calipers
Many photoetch sets include detailed brake discs with drilled or slotted patterns, plus separate caliper halves. These parts require careful painting but produce a stunning result behind the wheel spokes.
Exhaust Outlets and Tips
The 935’s side exhaust exits are a signature feature. Photoetch exhaust tips with realistic weld lines and thin walls look far more authentic than the plastic versions. Some sets also include heat shielding for the turbo area.
What to Look for When Buying Photoetch Parts
Not all photoetch sets are created equal. Here are factors to consider before purchasing:
Compatibility with Your Kit Version
Tamiya has released the 935 in multiple variants: the 1976 “Martini” Jägermeister, the 1978 Le Mans winner (with long tail), and the 1979 “Moby Dick” wide body. Ensure the photoetch set matches your specific version. Some sets are universal, while others are tailored to a particular release.
Material and Thickness
Most photoetch parts are brass or stainless steel. Brass is softer and easier to cut and shape but may require priming for paint adhesion. Stainless steel is harder and holds detail well but is more brittle. For delicate parts like grilles, brass is often preferred. Check the thickness—0.2mm is standard; thinner (0.1mm) can be used for very fine details.
Level of Detail
Some sets include only basic grilles and emblems. Others provide dozens of parts covering the entire car—from engine bay vents to windshield wipers. Decide how much detail you want and how much time you are willing to spend. A comprehensive set may cost more but saves you from buying multiple separate sets.
Instructions and Part Marking
Good photoetch sets come with clear instructions and numbered parts. Some manufacturers engrave part numbers on the fret. Sets without instructions require research to identify what goes where. For beginners, a set with a well-documented layout is recommended.
Application Tips for Photoetch Parts
Using photoetch parts requires patience and the right tools. Here are practical tips to get good results:
Tools You Will Need
- Sharp hobby knife or photoetch scissors
- Small metal file or sandpaper
- CA glue (superglue) or epoxy
- Tacky wax or tweezers for positioning
- Primer and paints suitable for metal
Cleaning and Preparation
Photoetch parts come with a thin layer of oil from the manufacturing process. Wash them in warm soapy water or degrease with isopropyl alcohol before painting. Handle parts by the edges to avoid fingerprints.
Cutting and Bending
Cut parts from the fret using a sharp blade—do not twist or tear. Use a bending tool or pliers with smooth jaws to create crisp folds, especially for corners of items like intake scoops. For curved parts, roll them gently around a cylindrical object like a drill bit.
Painting
Apply a thin coat of metal primer, then your chosen color. For bare metal look, leave parts unpainted or use a clear protective coat. For emblems, paint the entire part the base color, then carefully pick out details with a fine brush.
Assembly
Use superglue sparingly—a tiny drop is often enough. Position parts with tweezers and hold them in place until the glue sets. For smaller parts, use a pin vise or toothpick to apply glue precisely.
Recommended Photoetch Sets for the Tamiya Porsche 935
While we avoid naming specific shops, several manufacturers produce high-quality sets that repeatedly earn praise from builders. Look for sets from companies known for model car detail parts—they often release dedicated sets for the 935. Common options include:
- Basic upgrade sets that cover the most visible areas: front grille, brake ducts, emblems, and seat belts. These are ideal for beginners or those on a budget.
- Full detail sets that include everything from the engine bay (turbine housings, intercooler mesh) to the interior (pedals, steering wheel spokes) and exterior (door handles, window surrounds). These can double or triple the time spent on detailing.
- Custom or mixed sets from smaller producers that may offer unique parts like photoetch decals for the “Martini” stripes (though decals are beyond photoetch, some make metal stencils).
When choosing a set, read product descriptions carefully. Look for mentions of “photoetched parts for Tamiya 935 1/24” (the typical scale). If you are building the 1/12 version, ensure the set is scaled accordingly.
Final Recommendation
If you are building the Tamiya Porsche 935 and want to elevate it from a good kit to an outstanding model, invest in a dedicated photoetch set. Start with a medium-detail set that covers the most visible areas—grilles, badges, and seat belts. This avoids overwhelming you with too many parts while still making a noticeable difference.
For experienced modelers, a full detail set allows you to replicate the car to museum standards. Pay attention to the version of the kit you have and the set’s compatibility. With careful planning and patience, photoetch parts will give your Porsche 935 a level of realism that will impress at any competition or display.
Remember to take your time with each part. The metal components are fragile but rewarding. Clean your tools, use the right glue, and practice on spare frets if needed. The end result—a sharp, accurate, and detailed model—is well worth the effort.
