All those yellow brick sponges are the same. I guess it boils down to the application and what you're doing and for who. Dealers/OEM usually only pay for the removal of the contaminants, unless surface leveling is required. Keep in mind that you're doing a good pre-ABC wash and the dirt is removed from the surface which dramatically makes the sponge less damaging. Any marring that is visable only requires super light polishing to remove.
