I recently purchased the dual voltage powder coating gun and some powder. I’m preparing to coat a number of automotive chassis parts. As a test I coated a small steel bar. The bar was very rusted so I used glass bead to blast it to a silver color. The part seemed clean after I wiped it down. I then powder coated it following the directions on the powder. All seemed to be fine. A few days later I wanted to check the durability of the coating so I put it back in the blast cabinet and blasted it with the glass bead. I was able to remove the powder coating relatively quickly (about the same amount of work that was necessary to remove the previous coating and rust). I was wondering is this normal? My main reason for the test was I wanted to ensure I was doing things correctly before I started on the chassis parts.
