Newb here. Just throwing in my experience with plexiglass improvement. Almost all general aviation windows are high grade plexiglass. It follows the line of what you've all been discussing here. There is a kit product called
"MicroMesh". Ever finer specialized cloths with a foam rubber backing block. We are talking FAA approved repair for obtaining the ultimate visual perfection to hazed and crazed plexiglass products and their close kin.
Not cheap and not worth it for the individual probably but if you detail or are tasked with cleaning up a lot of plexiglass to like new condition there is nothing better!
