Frame Cleaning and Painting Prep

[ACK]

I took the bed off and in the process of cleaning the frame for painting with Hammerite. Looking at the project, a few questions came to mind that I can't find answers to in the forum ...

- Brake lines lines are in great shape, should I unclip them and don't paint?
- Trailing arms are newer, but the C-bolts and other suspension components have surface rust, should I remove and paint individually or paint everything in place.
- Going to paint the axle and brake backing plates. Should the transfer case cover be painted in place or removed and painted? Should I tape the bolts if painting in place?
- Wiring harness has been removed. Should the metal retaining clips be painted after they're cleaned up?

Seems like taking apart and painting individually is the right way to go ... but maybe I'm overthinking this.
