>>6173158Just take your time. Use circular motion, and check what you're doing often so that you don't overdo it. Polishing back to original look might take some time, but still easier and quicker than breaking out the paints.
Even if you don't use it for FA Gundam, it's a good trick to know how to do. Practice on a crap figure if you want. I do this to all the nub marks I see on all my toys anymore. (And then if the plastic is still too stressed, I might use hot water immersion to remove the stress mark, or, more commonly, mix up some matching paint.)
