Due to the many variables in the selection and end use of our products, we receive many inquiries for information related to metal finishing. In response to this, we have decided to add a frequently asked questions page as an additional support option. If the question or answer your looking for is not listed here, feel free to call our toll free support line @ (888) 424-2833 M-F 9:00 AM to 6:00 PM PST. We will be adding new information as it becomes available.
