I have been using this paint my elbow painted, but am not really happy with it. Despite sandblasting and fine grinding the paint layer is very rough and uneven. The paint is not really uniform and reminded ehrer on Light Grey Metallic than silver. He is also extremely sensitive. I have to paint after painting Extra about 30 minutes by hot air blower heated to harden around him, but nevertheless already hinterlies when installing a little touch obvious traces.
