This is an old thread, but I will post anyway.
People, you can do your own Cerakote.
It is childishly easy.
Buy a cheap air brush and a cheap harbor freight compressor with a water trap
If the finish on your gun is in factory new condition, just degrease according to the Cerakote instructions and apply the Cerakote right on top of the old finish.
Bake or air dry depending on if you bought Cerakote c or h
Use your home cooking oven (only when your wife is not home!)
If the finish is old, sandblast it off or hand sand with 120 grit sandpaper.
Degrease and spray.
Cerakote is a superior product in every way do duracoat
