Next I tried 24-30 inches , with lots of powder, all the way down to barely any power and it went all the way to this.
juuuust slightly better.
Cured: Note the square again
You can see there wasnt enough candy purple everywhere there was chrome underneat.
I did not touch the part on any area but the pointed end where I grounded for the candy purple, a place im ignoring in the pics
Hope this helps you see whats going on.
