Black out good chrome

What kind of time and temps did you bake the parts for? I have some old pipes with signs of light surface rust that I intended to clean up and black out, and have been wondering how I should prep them.

This thread makes me cry on the inside.

If this question was meant for me......

With chrome parts, I would bake them, before applying the powder, for 15 minutes longer than what was required for the powder that was going to be used, to see if any of the chrome was going to lift. If the chrome didn't lift, then I would prep the chrome parts as mentioned in my previous post, then shoot the powder and bake the parts. Most powders average anywhere from 25 to 45 minutes bake time. That time is figured from the time the part has reached the required bake temp. The time it takes to get the parts to the required temp doesn't count towards the bake time of the powder. If I remember correctly, most powders cured at 350f to 425f.
