A raw 3D print has layer lines; a finished one looks injection-molded. Sand the layers smooth with a progression of wet-and-dry paper, fill the surface with a filler primer, and rattle-can the color. A rotary tool carves seams and cleans supports. The finish is 90% patience and 10% paint — but the result looks like a bought object.

FAQ
Common questions about this kit
How do I remove layer lines?
Wet-sand with a progression — 220, 400, 800, then 1500 grit — under water so the paper does not clog. PLA sands well; PETG and ABS even better. Patience and a flat block beat rushing with power tools.
Why filler primer?
Rattle-can primer fills the tiny valleys between layers so the color coat goes on a smooth surface. Two to three primer coats, sanded between, is what hides the print. Skip it and every layer shows through the paint.
Can I paint PLA directly?
Lightly — but the paint accentuates layer lines, so sand first. Use a primer meant for plastic. Acrylic craft paint with a clear coat also works for details and small parts.
What is the rotary tool for?
Cleaning out supports from tight spaces, carving panel lines, and light shaping. It is the power sander for spots your fingers cannot reach. Use low speed so you melt, not gouge, the plastic.

Print finishing and my game art share the polish-is-patience gospel — wet-sanding the layers is the same as retopologizing a mesh. The filler primer hiding the print is the normal map hiding the low-poly, agreed.
