The SnakeSkin Superfinish is an ultimate and economic solution that can serve the purposes of any company that acts in the engine valves market, wishing to offer its range of customers with a wider selection and an opportunity to purchase upgraded valves at affordable prices.

It has also been proven that when the SnakeSkin Superfinish is deposited on valves that were initially treated with a PVD coating, a far greater value will be obtained. The reason for this fact, is that the SnakeSkin Superfinish deposition doesn’t subtract any property achieved by any coating process, therefore a phenomenon of properties incorporation accurse and the end product becomes far more superior then it should have been if it was treated with a coating process alone.
