Powder coating is an advanced method of applying a decorative and protective finish to metals. The powder used for the process is a mixture of finely ground particles of pigment and resin, which is sprayed onto a surface to be coated. The charged powder particles adhere to the electrically grounded surfaces until heated and fused into a smooth coating in a curing oven. The result is a uniform, durable, high-quality, and attractive finish. Powder coating is the fastest-growing finishing technology in North America, representing over 10% of all industrial finishing applications.
We can powder coat many different colors. Please specify the color you'd like to have your valve cover powder coated in the Comments field.
Options:
New OEM Core - Use this option if you would like a brand new valve cover to be coated.
Customer Supplied Core - Use this option if you will be sending us a core. NOTE: If the valve cover you send in requires more cleanup than normal, you will be charged a $65 cleanup fee before it ships back to you. Avoid this fee by sending us a relatively clean, corrosion-free valve cover.
Refundable Core Charge - Use this option if you would like us to powder coat one of our cores for you. When we receive your metal core back from you, we will refund this charge. PLEASE NOTE: If your core is damaged or dirty, we reserve the right to reject the core or give a reduced refund.
NOTE: We can only powder coat metal valve covers, like those found on the 2008 models.
