<p>[QUOTE="rlm's cents, post: 2043410, member: 7957"]Nope! The key here is "polish in the crevices". Yes, you can take a knife and scratch into most crevices. Funny, but that does not make a polished surface. So you take something finer to polish and it requires speed. Now these if bristles (or whatever you choose to call them) are fine enough to get into the minute crevice, they are so soft they will not polish the crevices because they fly over the depths. If they are stiff enough to get into the crevice, they make big scratches and require excessive force so the surface becomes massively distorted and scratched. There is nothing that will both polish and not scratch or if you know of it, patent it and become rich.[/QUOTE]</p><p><br /></p>
