If you want your paint to stick, look clean, and stay durable, prep matters. This guide covers a simple workflow for unpainted resin 3D printed military vehicle miniatures (tanks, IFVs, APCs, artillery, and air defense vehicles).
Miniwaves models ship fully washed and fully cured, with supports removed. Most models only need very light cleanup before priming.
Tools you’ll want (basic)
-
hobby knife or sprue cutters (for tiny nubs)
-
fine sandpaper or sanding sticks
-
primer (your preference)
-
optional: small files for tight areas
You don’t need a full workshop. This is light finishing.
Step 1: Inspect the parts (30 seconds)
Before sanding:
-
check that the model sits flat
-
look for tiny support nubs (small raised dots)
-
identify fragile details (guns, antennas, thin barrels)
Because many models are multi-part (hull + turret), dry-fit parts so you understand how they sit before paint.
Step 2: Remove small support nubs (light cleanup)
This is the only “prep” most customers need:
-
shave the nub gently with a knife, or
-
sand lightly until smooth
Do not over-sand. The goal is to remove the nub without rounding off sharp edges and detail.
Step 3: Optional quick rinse (only if you want to)
Your model is already washed and cured, so you’re only removing sanding dust. Some painters still like a quick rinse and dry before primer. If you do it, make sure the model is fully dry before priming.
Step 4: Prime (don’t bury the detail)
Primer is the bridge between resin and paint. Use light coats:
-
one light coat
-
let it dry
-
a second light coat if needed
Heavy primer will fill fine details (and your models are all about detail).
Step 5: Paint, weather, and seal
After painting, consider a protective clear coat, especially if the miniature will be handled for tabletop use.
Common mistakes (avoid these)
-
skipping primer
-
thick primer coats that bury detail
-
aggressive sanding that destroys edges
-
rushing drying time between steps
