After the AC box was back in, I decided to take a look at the drip rail to see how difficult it would be to remove. Tried to pry a little of the old, dried, separated seam sealer, and before I knew it, I had most of it out. And, I had told my wife that I was going to wait on that job.
Most of it came out fairly easily, then I attacked it with a wire wheel. Some surface rust, but no holes and no rust through!!
So, decided to use some rust reformer just to make sure there wasn't something hidden, so masked it all up and shot a coat on it.
The goal is to let this cure overnight, then tomorrow evening I am planning to attempt to redo the seam sealer. I have the 3M 8307 for the horizontal section, then 8308 for the vertical sections. Never done seam sealer before, so it should be interesting...
