    1. Any powdercoating experts here? Facing issues with powdercoating on top of zinc plated mild steel.

      I've been having issues with powdercoating on top of zinc plated mild steel sometimes. Have issues like small dots visible instead of a smooth texture.

      It looks like how a zit or pimple looks on the skin.

      After zinc plating, it is pre heated for 15 mins at 150 degrees celsius. Then sand it with some 80 no sandpaper. Finally powder coat it and cure it again for 20 mins.

      Amy inputs would be appreciated. Thanks guys.

      I know there are some Germans on Tildes, figure at least one of y’all might know. How does a typical Autobahn differ from a typical Interstate in design and construction? How often is repair work done and how long does it last? What work would be required to upgrade an Interstate to Autobahn standards?
