Hole of the day.

See those pesky hallow part from Bandai ? Here how I fix them up real quick and ready to paint within 5-10 minutes.

Uhhh...holes...

Fill it up with some pla plate chips.

Pour in some baby powder+CA glue to fill the rest of the gap. During the cure time place the filled part facing down.

Ready to sand it within 5-10 minutes. Or you can fill it up with option parts. :P
