Drip rail caulk?

I pulled the chrome, used screwdrivers and finished it off with a wire wheel on a drill and did both sides in about 30 minutes. (wife's 72 Dart)

About 2 years ago I posted that I was going to do an experiment with my own car where I removed about a foot of the caulking, wire brushed it clean and gave the seam a good heavy coating of Eastwood's rust encapsulator. (the stuff dries hard as hell)
Once dried I painted over the seam, then put the chrome back on.
Everyone told me it wouldn't work, that it would leak and so on, but after two years that spot still looks like it could have been done last week.
I watched it pretty close through 2 winters now, so I'm satisfied it'll hold up but knew I could use caulk pretty much any time if it looked sketchy at all.
This is the way I'm going to do the rest since seam sealer and pretty much everything else I have ever seen ends up pulling away and letting water in around it at some point.
