Have been busy scrubbing the yellow stains off the top-edge of my 2001 Intrigue, which developed due to clear coat failure, and the previous owner allowing it to chalk.
In the process, I'm finding a puzzle in the "seam" that protrudes where the roof and side walls meet. If I were designing that joint, I'd be tempted to make the roof lap down over the sidewall. I would even make an expanded ridge all around the coach, to do just that.
But I find my coach has at least TWO applications of caulk along the upper edge of that ridge. The first is clear caulk, with a smattering of what look like algae growths as pin-point black spots, then the top coat is white caulk, which actually formed a very poor, or even, no seal at all along much of the ridge.

Can anyone tell me, is the structure built with an open seam at the TOP of that ridge, requiring caulking, or did previous attempts to seal things result in overkill?
