<p>[QUOTE="playpossum0985, post: 7932552, member: 23806"]Also, if these flaws came from the heavy steel rollers that sized the sheet, or were used in the lamination process, the friction would build up heat on an already hot blank sheet. This could easily overheat the cladding and cause the discoloration. A dirty roller (if rolling) would leave some impressions, but can only leave drag marks if they are locked up or stopped.[/QUOTE]</p><p><br /></p>
