🏁 Introduction
Imagine opening a can of paint, pouring it directly into your spray gun, and transforming your ride — no mixing, no reducers, no hardeners. That’s the beauty of the Dupli-Color Paint Shop Finish System.
This lacquer-based system includes primer, color, and clear coat, all pre-reduced and ready to spray. It dries quickly, buffs easily, and is designed for DIY automotive projects that can rival a professional shop finish.
🛠 Step 1 – Preparation is Everything
Before you ever spray, the vehicle’s body must be completely ready. That means:
- Finish all bodywork — dents, scratches, rust, and flaking paint must be addressed.
- Clean thoroughly — remove dirt, grease, and wax with a mild cleaner and water.
- Sand the surface — use 400–600 grit sandpaper or a red scuff pad to feather edges.
- Special plastics need adhesion promoter — Dupli-Color CP199 is recommended.
- Mask everything — anything not being painted must be covered.
- Final wipe-down — use Dupli-Color Multi-Purpose Foaming Prep Cleaner to remove oils and dust.
🔑 Pro Tip: If your surface isn’t spotless, every speck of dust or grease will show through the primer, color, and clear. Cleanliness makes or breaks your finish.
🎨 Step 2 – Primer Application
Primer is your foundation — it evens out all the surface colors and creates a smooth base for paint.
- Shake and strain the paint before loading it into your spray gun.
- Spray at 25–30 PSI using a 1.4mm HVLP tip.
- Apply 2–3 medium coats, overlapping each pass by 50%.
- Allow 5–10 minutes between coats.
- After drying, lightly sand out imperfections with 600 grit paper, then clean again.
The result: a uniform gray foundation, ready for color.
🎨 Step 3 – Laying Down Color
Now comes the fun part — spraying the actual paint. In the video, the team uses Concrete Gray, a modern OEM-style color.
- Pour paint directly from the can (after straining) into the spray gun.
- Apply 2–3 coats. The first should be light, with later coats heavier for full coverage.
- Maintain 8–10 inches spray distance.
- If spraying a metallic color:
- Hold the gun a bit farther back (10–12 inches).
- Finish with a light mist coat at 12–14 inches to evenly distribute metallic flakes.
- If imperfections appear, lightly wet sand with 1000 grit and wipe down again.
✨ Step 4 – Protecting with Clear Coat
The clear coat gives durability, UV protection, and the glossy look.
- Apply 3–4 coats, starting with a light one and building heavier.
- Maintain 8–10 inches spray distance.
- Final coat should be the heaviest with about 75% overlap to maximize gloss.
- Add extra coats if you plan to wet sand and buff later.
- Always clean your spray gun immediately afterward with lacquer thinner, acetone, or prep spray.
🔧 Step 5 – Final Finish
After the clear coat cures, inspect the surface:
- Any dust, runs, or orange peel can be wet sanded and then buffed.
- Buffing stages bring out the final deep gloss finish.
- Always wear a respirator and ensure proper ventilation throughout the job.
In the example, the 1979 El Camino emerges in Concrete Gray with Jet Black accents, looking showroom-ready thanks to the Paint Shop system.
