<p>[QUOTE=&quot;lkeigwin, post: 1189756, member: 30400&quot;]Whizzing doesn&#039;t leave hair lines, FWIW. Surfaces are usually dazzling but the luster is all wrong.

Parallel faint lines that cross devices is a give away. Hair lines that do not cross devices are usually due to die maintenance (often called polish lines, a little too loosely). Random hair lines over devices can be rub from circulation so they are not always fatal.</p><p>Lance.[/QUOTE]</p><p><br /></p>
