I really like these.
Griots carries the small round ones you can use with buffer.
Don't see them offered through AG Griots, or anywhere on AG.
Help please?
I can attest to the quality of the first two I linked. The first one is good for tar and other really heavy contamination. The second one is good for bugs and is very soft and gentle - I use this Bug Sponge during every wash to pre-scrub dirty side skirts and paint behind the wheels. The third one is marketed for cleaning glass, but the specifications say that it is also safe for paint, chrome, and plastic.
