Quick answer

Gundam Color UG07 Exam Blue 1 is a solvent-based acrylic paint by Mr. Hobby, ideal for both hand brushing and airbrushing. For best results, thin it with Mr. Color Thinner, apply in thin coats, and let each coat dry fully before the next. The 18ml bottle is enough for one 1/144 scale kit or several small parts.

What Makes UG07 Exam Blue 1 Special?

Gundam Color UG07 Exam Blue 1 is part of Mr. Hobby's Gundam Color line, formulated to match the official blue used in the Gundam universe. It's a solvent-based acrylic, meaning it dries quickly and offers excellent adhesion and color richness. The 18ml bottle is a convenient size for touch-ups or small projects.

Unlike some hobby paints, UG07 is designed to work well both straight from the bottle (for brushing) and thinned (for airbrushing). The paint levels nicely and resists brush marks when applied correctly. Its quick-drying nature also helps speed up painting sessions.

Before You Start: Surface Preparation

For best adhesion, prime your parts with a primer suited for solvent-based paints. Mr. Hobby's Mr. Surfacer or a fine gray primer works well. Let the primer cure for at least 24 hours for maximum hardness.

If you're painting over bare plastic, wash the parts with mild soap and water to remove mold release agents. Dry thoroughly before painting.

Step-by-Step: Painting with UG07 Exam Blue 1

  1. Step 1: Shake the bottle thoroughly: Solvent-based paints separate over time. Shake the 18ml bottle for at least 30 seconds until the pigment is fully mixed. Check the bottom of the bottle for settled pigment. Common mistake: not shaking enough leads to uneven color and poor coverage.
  2. Step 2: Thin the paint (if airbrushing): For airbrushing, thin UG07 with Mr. Color Thinner at a 1:1 to 1:1.5 ratio (paint to thinner). For hand brushing, use the paint straight from the bottle or thin very slightly (1:0.2) to improve flow. Checkpoint: if the paint spatters or clogs, it's too thick. If it runs or pools, it's too thin.
  3. Step 3: Apply the first coat: For hand brushing, use a soft, flat brush and apply in one direction. For airbrushing, hold the brush 4-6 inches away and apply a light, even mist coat. Let dry for 10-15 minutes. Common mistake: applying too thick a coat causes drips and loss of detail.
  4. Step 4: Apply subsequent coats: After the first coat is dry to the touch, apply 2-3 more thin coats, allowing each to dry. Build up the color gradually for a smooth, even finish. Checkpoint: if you see brush marks or orange peel, your coats are too thick or you're brushing over partially dry paint.
  5. Step 5: Clean up immediately: Clean your brush or airbrush with Mr. Color Thinner or a dedicated solvent cleaner. Do not let paint dry in the brush or nozzle, as it can ruin the tool. Common mistake: delaying cleanup leads to clogged airbrush nozzles and ruined brushes.
