Refinishing convertible top frame?

A lot of restorers clean and carefully repaint top frames. Some here on the BB have powder coated the parts. Since the frame is well shielded from the weather - by the top! - and usually has no gravel being kicked up at it, it seems that powder coating is not needed.

Any opinions, or more importantly, any experience with either approach

Thanks

Just a note: Osso, how did you approach this on your magnificent restoration?

I had the frame powder coated, Robert. If you go that route, take pictures of the components and print it out to give to the powder coater. They will love you for it.

I replaced my convertible top last winter. After I removed the old top, I noticed that the frame had quite a bit of rust in places. So I first used a nylon brush on a drill motor to knock the loose and heavy corrosion off, then hand sanded with 150 grit followed by 220 grit sandpaper.
Prior to applying any paint, I cleaned the frame with POR-15 Marine Clean, then used their Metal Prep (etch) product. A thourogh rinse with plain water followed both of these treatments.
After allowing a couple of days for the frame to thoroughly dry, I brush painted it with two coats of POR-15 SemiGloss Black topcoat, making sure not to get paint into the pivot points.
When it dried the paint was quite hard with superior adhesion.
I would do the same thing again.
Edit: I also carefully lubricated each of the hinge pivot points with a needle-tipped oil bottle prior to installing the new cloth top.
