      I can't see your pics, but judging from the thread title you're having trouble with edge coverage. You can take a file to the edges and go over them to create a slight bevel. Edge coverage can be tough, especially on laser cut parts. Also pay attention to how the parts hang.

        Yep, either knock'em off or go to a different type powder. Can't remember which type it is.. but the one type doesn't like edges.

            I think it might be the black powder , the red ones look fine.
            I have done those parts lots and lots of times and never had any problem with edges.
            you can also try a second coat.

              yeah---most powders don't really like fine 90 deg (or approximate) angles. knock down the edge first, then shoot. don't worry about the sprocket edges as the powder will be removed by the chain travel anyway.

                Do you know the type resin of the powder you used? What kv did you shoot at, what was the gun to part distance you sparayed at?
