Hello again, fellow curmudgeons, I sent out more shipping notices this morning and plan to hit the PO in about 5 hours. When you receive your plates and prior to mounting, please clean them with soap and water or even windex or simple green. I cleaned the machine oil off to the limit of my patience but there might be a little left. I’ve not seen any interaction between the machine oil, windex, etc with the coating. Regards, Jerry
