This is probably the new thing I've tried recently.

It was more difficult than I expected.
In particular, I made the mistake of not stirring the paint properly before applying it, which caused scratches on the clear parts and made it look uneven, forcing me to repaint several surfaces. This was a valuable lesson for next time.

For most people, I think using a spray can is better than a brush, especially for single colors, as it eliminates unevenness if you put in the effort to mask the area properly.
