cut it out,drill it out,coat the inside with a rust ihibitor or a product like por15 should help,but eventually all trucks need cab corners and rocker panels.Your truck is starting to experince pain,its time to sypathize and but her something new.

When I bought my truck four years ago, my cab corners had barely started to rust. I wire brushed them, sprayed them with brake cleaner, and coated the whole inside with rust inhibitor from Eastwood, seam sealer, and brush-on undercoating. They were so watertight that a year later I noticed that they were holding water (I could only get my hand in the passenger side w/ the gas tank back in), so I drilled two drain holes, one in the front, one in the rear. So far, no signs of rust showing through on my daily driver. Hope I didn't hurt my corners worse by sealing them too well, but let my stupidity be your teacher.

Food for Thought.

With my truck, I am going way overboard on making ma cab as quiet is I can, and I plan on sealing the bottom of the cab corners (which have an open seam for drainage). So, after I close up the sheetmetal, I will then drill a hole the size of the normal rubber plugs that you find on later model cars and trucks, and put plugs in each cab corner. That way, if any waters gets into my cab, I jsut have to remove, drain, replace.
