chefwong- IMO you're right about the potential cleaning action of "nonabrasive/non-cleaner" glazes. The stuff will at the very least affect some degree of solvent action on the surface being worked (even *water* could do this). Whether or not it'll be enough of a solvent action to matter
#7 is a good example- way back in the day (i.e., 1970s) I used it as a gentle cleaner on ss black lacquer- it *did* clean the paint, you could see the dirt on the polishing media.
For that matter, even LSPs like
Souveran can do a *little* cleaning. Who hasn't seen a little dirt show up on their wax applicator pad at one time or another
themightytimmah- You're right! Another thing we used to do is apply #7 with terry...on very soft ss lacquer it would do a *little* correction. It was the final "abrasive" step in the process that used to be called a "hand-rubbed lacquer finish".
