>>9557438these glass nano polishing files are pretty good for lazy nub removing and all around fun. (theyre made for buffing womens fingernails and are like $3 on amazon.) i found out about them doing gundams.
the surface is pitted so it will scrape away any raised surface nub. it's also smooth glass so it wont scratch whats underneath. it would work really good for cockpit canopies or other clear parts
