How to blunt Gundam and how to handle the nozzle perfectly? I always polish it smooth and then make it a little white.

If it is dull, you need to spray matte paint, which needs to be the last step after everything is done. It is recommended to use Jiaya's anti-ultraviolet matting paint. Imported paint is relatively cheap and cost-effective.

If the nozzle is handled perfectly, it is nothing more than a few simple steps, but it needs to be done more carefully.

First of all, when cutting, try to keep the nozzle as long as possible. Then repair the nozzle with a pencil sharpener or single-edged scissors. You can't worry about this step, you can't cut it off at once, you have to cut it bit by bit, layer by layer. When the remaining time is less than 1mm, grinding will begin roughly. When polishing, I prefer to dip the water sandpaper in water, which requires you to use a sander to stretch the water sandpaper on the sander. First, smooth the nozzle with 800 mesh, then treat the abrasion marks with 2000 mesh, and finally wipe it with polishing cloth, and almost no abrasion marks can be seen.

Because matte paint will be sprayed in the end, we don't need to pay too much attention to polishing here, as long as the wear marks are treated to be slightly inconspicuous.
