A Complete Beginner-to-Advanced Guide for Professional Results

The Paint You Choose Matters More Than You Think
One of the biggest questions we hear from builders who are new to resin model kits is simple:
“What paint should I use?”
It’s a great question because resin behaves differently than traditional injection-molded plastic. The good news is that modern resin accepts paint extremely well—provided the surface is prepared correctly.
Whether you’re building your first resin pulling tractor, drag truck, monster bus, or custom race vehicle, understanding your paint options can make the difference between a model that looks good and one that truly stands out.
At Adrenaline Junkies Model Kits (AJ Model Kits), every kit is designed with one goal in mind: giving builders the freedom to create something uniquely their own. Paint is one of the most powerful tools you have to bring that vision to life.
Why Resin Needs a Different Approach
Unlike injection-molded plastic, resin parts are produced layer by layer using modern 3D printing technology. During manufacturing, parts are cleaned, cured, and carefully inspected before packaging. Even with that process, tiny amounts of oils from handling or residual contaminants can remain on the surface.
That’s why preparation is the first—and arguably the most important—step before paint ever touches your model.
Skipping preparation can lead to:
- Paint lifting
- Fish-eye imperfections
- Poor adhesion
- Uneven color coverage
- Premature chipping
Fortunately, avoiding these problems is simple.
Step One: Wash Every Part
Before cutting supports or assembling your kit, wash every resin part using:
- Warm water
- A few drops of dish soap
- A soft toothbrush
This removes dust, oils, and handling residue while giving your primer the best possible surface to bond to.
Allow everything to dry completely before moving on.
Primer Is Not Optional
One of the biggest mistakes beginners make is spraying color directly onto resin.
Primer serves several important purposes:
- Creates a surface paint can grip
- Reveals sanding imperfections
- Produces consistent color
- Improves durability
- Helps metallics and bright colors look their best
Think of primer as the foundation of your entire paint job.
Choosing the Right Primer
Not all primers are created equal.
Here are some of the most popular choices among experienced builders.
Gray Primer
The best all-around option.
Perfect for:
- Race cars
- Pulling tractors
- Trucks
- Engines
- Chassis
Gray highlights imperfections without dramatically affecting final color.
White Primer
Ideal for:
- Yellow
- Orange
- Lime Green
- Bright Red
- Fluorescent colors
Because white reflects more light, bright colors require fewer coats and appear much more vibrant.
Black Primer
Perfect for:
- Metallic finishes
- Chrome effects
- Dark vehicles
- Engine components
Many builders use black primer under metallic paints to create additional depth.
Acrylic Paints
Acrylics are excellent for beginners.
Advantages include:
- Low odor
- Fast drying
- Easy cleanup
- Airbrush friendly
- Brush friendly
Modern acrylics have become extremely durable and produce outstanding finishes.
They’re especially useful for interiors, engines, detail painting, and weathering.
Enamel Paints
Enamels remain popular with experienced builders because they:
- Level beautifully
- Produce smooth finishes
- Offer excellent durability
The trade-off is longer drying times.
Many builders still prefer enamels for bodies requiring an ultra-smooth finish.
Lacquer Paints
If you’re looking for a show-quality finish, lacquer paints remain the benchmark.
Benefits include:
- Extremely smooth finish
- Excellent gloss
- Fast curing
- Outstanding polishing potential
Because lacquers are hotter than acrylics, they should always be applied over a properly cured primer.
Airbrush or Spray Can?
One question never seems to disappear.
Should I buy an airbrush?
The answer depends on your goals.
Spray Cans
Perfect for:
- Beginners
- Single-color builds
- Large body panels
- Quick projects
Today’s hobby spray paints produce impressive results with proper technique.
Airbrushes
Offer greater control over:
- Fine details
- Fade effects
- Candy colors
- Flames
- Weathering
- Clear coats
While the initial investment is higher, an airbrush quickly becomes one of the most valuable tools in any workshop.
Thin Coats Always Win
Regardless of the paint you choose, resist the temptation to spray heavy coats.
Professional builders build color gradually.
Several light coats will always outperform one heavy coat by reducing:
- Runs
- Orange peel
- Dust contamination
- Lost surface detail
Patience produces better models.
Don’t Forget the Details
Once the body is complete, smaller components deserve just as much attention.
Consider painting separately:
- Suspension
- Engines
- Roll cages
- Seats
- Steering wheels
- Fuel systems
- Exhaust headers
These small details transform a good model into an unforgettable one.
The AJ Model Kits Philosophy
At Adrenaline Junkies Model Kits, we intentionally leave room for creativity.
Our kits are designed to provide a solid foundation while allowing every builder to personalize the final product.
One builder may create a factory-fresh showpiece.
Another may build a mud-covered pulling tractor with years of wear.
Neither approach is wrong.
That’s what makes this hobby so rewarding.
Every finished model tells the story of the builder behind it.
Looking Ahead
Now that you’ve chosen the right paint, it’s time to protect your finish and add the details that make every build unique.
In the next installment of The Builder’s Handbook, we’ll explore:
Applying Water-Slide Decals Like a Professional
You’ll learn:
- Surface preparation
- Setting solutions

- Multi-piece decal alignment
- Sealing decals for a long-lasting finish
Whether you’re applying factory stripes or custom AJ Model Kits graphics, proper decal placement can completely transform your finished build.
Build the Dream
Painting is one of the most rewarding parts of scale modeling because it’s where a collection of resin parts begins to take on its own identity.
With proper preparation, quality primer, and patience, even your very first resin model can produce results you’ll be proud to display.
At Adrenaline Junkies Model Kits, we’re honored to be part of that journey. Every resin kit we design is built with one purpose—to give you the freedom to create something uniquely yours.
