Works as poor mans car detailing clay bar. Ends up getting soft after ingesting too much spray detailer but that container is like $3 versus $20 for a clay bar 1/20th the size so you can throw each piece away after a few passes.
Also when you have that much material and you can throw dirty pieces out liberally, contamination and swirl marks are less likely.
