The DIY Option – Make Snading Sticks yourself

While you may have great success using custom sanding sticks, you can also save money by learning to customize a homemade sanding stick for your Gunpla kit. Here’s how to do it. 

What you need

  • Plastic popsicle sticks 
  • Outdoor double-sided tape or glue
  • Sandpaper (400 to 3000 grit)
  • Hobby knife or scissors
  • Marker

Instructions – DIY Sanding Sticks For Gunpla

  1. Cut the length of the tape to be a bit shorter than the popsicle stick. Then, cut it in half lengthwise to get two narrow strips. 
  2. Stick one part of the tape on the popsicle stick and the other on its other side 
  3. Take the sandpaper and stick it to both sides. You’ll have extras on the edges. 
  4. Use a knife and cut along the edge of the stick, and you’ve got yourself a homemade sanding stick. 
  5. Use a marker to label the stick with its grit for easy identification.

Use a six-way nail buffer (Not My Favourite, But Still An Option)

If you can’t get your hands on a sanding stick, or can’t afford to stress yourself making one, use nail six-way nail buffer. They are available from your friendly supermarket.  

Nail buffers are very cheap and can be washed. Plus, they are soft enough, so you can cut them up into various shapes to reach those hard-to-get places. 

And, their six corners mean you can easily switch from fine to medium and coarse grits when sanding your models. 

What grit is best for gunpla?

It depends. 

When I sand my Gunpla kits, I start with 600 grit and usually end with 1000. I sometimes even start with 400 to get the job done faster. But, you can also start lower when you need to shave off a lot of plastic (usually 120-240) and work your way up to 400, 800, then 2000. 

If you’re sanding for painting your Gunpla model and want to be extra safe, you need to start low until you can see that the joints aren’t touching, except where they join together. 

To use Gunpla sanding sticks effectively, follow these step-by-step instructions:

  1. Choose the right grit size: Start by selecting the right grit size sanding stick based on the part of the model you are working on. For example, use a coarse grit (around 120-240) for removing large imperfections or excess material, and a finer grit (400-800) for polishing or refining the surface.
  2. Hold the sanding stick correctly: Hold the sanding stick firmly but not too tightly, using a comfortable grip that allows you to control the pressure and direction of the sanding motion.
  3. Sand in one direction: Always sand in one direction, rather than back and forth or in circular motions. This helps to prevent scratches or unevenness on the model’s surface. Typically, you should sand in the direction of the panel lines, or along the length of the part.
  4. Use light pressure: Use light pressure when sanding to avoid damaging the model or removing too much material. Let the grit of the sanding stick do the work for you.
  5. Check your progress: Check your progress regularly by wiping the surface with a cloth or blowing away any dust. This will help you to see where you need to focus your sanding efforts and avoid over-sanding.
  6. Move on to finer grits: Once you have achieved the desired level of smoothness with a coarser grit, move on to finer grits gradually, repeating the same steps until you reach the desired level of smoothness and finish.

By following these steps, you can use Gunpla sanding sticks effectively to achieve a high-quality finish without damaging your model. Remember to be patient and take your time, and always use the correct technique to get the best results.


Painting small details on your Gunpla kit is not all about perfection, but it isn’t always bad to want an exceptional finish on your Gunpla kit.
