Cleco pins are a definite must for sheet metal fabrication. They're basically spring-loaded, removable pop rivets that allow you to hold two pieces of sheet metal together in proper alignment for drilling or riveting. They work great for Circle Track use for test-fitting panels before they're permanently attached to your vehicle.
Used 7 on heavily oxidized Airstream. Sanded off oxidation. Presto changeo, an almost mirror-like finish. Will stick with Nuvite. Important to follow instructional video.
This is an amazing aid to my fisning. Something serious inland fishermen should have. My only regret is that I didn't have this over the last 20 years.
