Engine turning, or damascening, has long been the hallmark of fine automotive craftsmanship. This technique leaves metal surfaces with a swirled pattern, really setting off your vehicle. Great for any flat polished metal surface: firewalls, valve covers, dashboards. Either of these two Kits will allow you to customize your vehicle with this process using specially formulated abrasive rolls and your drill press. Two Kits are available: the 1in. Kit contains two 1in. diameter rolls and mandrel; the 1/2in. Kit contains two 6in. long rolls, which yield six 2in. working rolls. Complete instructions included.
