🚧 Step 1: Prep Like a Pro

The foundation of a great finish starts before any paint or stickers go on.

• ✅ Leave the outer protective film ON
• This protects your body from scratches during cutting, masking, and painting
• Keep it on until the very end for best results
• ✏️ Mark your cut lines clearly
• Use a marker to outline:
• Cut lines
• Window masks
• This makes everything much easier to see when working with clear polycarbonate
• 🔪 Use a sharp blade for clean cuts
• Score the body first, then snap it along the line
• Scissors are okay for simple cuts but struggle with tight curves
• 🪵 Sand for precision
• Use sandpaper with a backing block for straight edges
• Use a spray can or pen as a curved backing for rounded areas
• Smooth out any rough edges to:
• Improve appearance
• Prevent cracks and tears later

🧼 Step 2: Clean Before Paint

A clean surface is critical for paint adhesion.

• 🚿 Wash the inside of the body with:
• Dish soap
• Warm water
• 💧 Let it air dry naturally
• Avoid cloths or paper towels that can leave dust or oils

🎨 Step 3: Masking and Painting (Where the Magic Happens)

This is where patience pays off.

Masking

• Apply window masks on the inside
• Use Tamiya masking tape for custom designs
• Press down all edges firmly
• Prevents paint bleed under masks

Painting

• 🔥 Warm your paint
• Place spray can in lukewarm water, this is the best way to heat the spray can and contents evenly
• Helps with smoother spray and consistent pressure
• ⚠️ Only use Tamiya PS paint
• Designed specifically for polycarbonate bodies
• Other paints can crack or peel
• 🎯 Application tips
• Start with a light mist coat
• Wait 10–15 minutes between coats
• Apply thicker coats after the first layer
• 🕳️ Spray deep areas first
• These are hardest to reach later
• Avoid missing hidden spots
• ⏳ Once fully dry:
• Carefully remove all masks
• ✅ Still leave the protective film ON
• It continues to protect during the next stage

🏁 Step 4: Sticker Application (The Finishing Touch)

This step can make or break the look of your build.

Preparation

• 🔢 Number the back of each sticker
• Makes identification quick and easy
• ✂️ Use decal scissors
• Allows precise trimming close to the edge
• 🔵 Round off sharp sticker corners
• Reduces peeling over time

Application Technique

• 📍 Position before committing
• Keep backing on
• Use Tamiya tape to hold sticker in place
• 🔄 Hinge method
• Tape one edge
• Fold sticker back
• Peel backing and roll sticker into place
• 📏 Overlapping stickers
• Apply lower numbered sticker first

Final Trim

• ✂️ Trim any excess that goes past body edges
• ❌ Do NOT fold stickers inside the body
• They will peel over time

🎯 Final Step: The Big Reveal

Now for the most satisfying part…

• 🎉 Remove the outer protective film
• This reveals a clean, glossy finish underneath
• All that care pays off instantly

💡 Key Takeaways

• Leave protective film on as long as possible
• Clean prep leads to better paint adhesion
• Light coats and patience beat rushing every time
• Precision cutting and sanding improves durability
• Proper sticker technique = longer lasting finish
