How to clean inside of Rocker Panels

[th3blue]

for clogged sunroof drains I normally use air tools and high pressure to clear the lines out.

Inside the Rocker Panel... Is that not where the Front Sunroof Drains drain into? Or am I mistaken?

I was under the impression that the front sunroof drains went straight down to the holes in front of the doors, but it appears I was mistaken? The thing is, if there indeed is a whole boxed part of the monocoque that is being used as a holding tank (effectively) we should have so many reports of rusting it wouldn't even be funny: does anyone have a picture of a section?

ah, its something you will never need to deal with where you live. up here in the rust belt, there's something called anti-rust treatment. they basically shoot the underside of the body and the inside of the body panels with oily or waxy substances to protect from rust in winter. but since the rocker panels are a top target for rust, they drill a couple of 1/2" holes in the door jambs and spray some oil in there.

Hmm.. Didn't know that...
