WARNING Due to the nature of product, some scratches and blemishes should be expected. Metal sheets, just like their antique counterparts, may contain a certain amount of flaws, smudges, and scratches especial after shipping. Most of these can be buffed off using 0000 Steel Wool. Typically after the sheet has been cut and fabricated into the final area, a patina or finish is achieved and so most of those marks will be buffed off anyways. Do not expect to get a perfectly clean sheet. IMPORTANT make sure you un roll and reverse lay the sheet to help it relax and flatten back out faster. You also may apply some heat to help relax it.
