Powder coating is also known for hiding cracks, especially in welded areas.
Before I found this out I had my nose gear mount and rudder pedals
powdercoated. I was happy with the finish until I started handling and
installing
the
parts. The tubing was zinc coated to start with (shiney, gold finish) and now
the
powder coat is chipping off. I will likely scuff sand and repaint with Corlar
primer, then a top coat.
