Hey, just real quick, should I shave and sand the nubs of my gunpla as I build them, or after?
It depends on A: the size of the nub, B: the location of the nub, and C: how visible it is.
The bigger and more visible, take it off before using the piece.
The smaller, less visible, and not on any important spot hindering the structure?
It’s really up to personal choice, though.
If the nubs are undergated I wouldn’t worry about it. If they are snipped and sheared the plastic so it looks kinda white, I would shave them or sand them down.
However all on personal preference.
I usually shave and sand while building, but now that i think about it maybe I should try doing it after.
