I forgot that detail. I put a countersink in the back of the disc. Since the "tail" of the pop rivet is hollow and quite thin, it is easy to use a punch to flatten it into the countersink. The 3M tape is relatively thick, so the countersink may not be necessary, but to me it makes a nice touch.
There is no snap on the waterfall. There are four across the inside of the trunk, three along the base of the windscreen, and one under each mirror. I looked at the pictures and didn't see anything. Which picture? A reflection maybe?
All of the fading is down to sun exposure, as I only occasionally wash the cover, and then in the same Tide white bottle that i wash regular clothes in.
The sad thing is that I have the correct thread, but it is on the same type of bobbin as the "other stuff". and I simply grabbed the wrong one. They are now labeled more clearly.
