No concerns with the panels coming off - except in an accident, in which case these are low on the concerns list. They are very solidly attached - while still removable with some effort.
I've used black and clear Dual Lock. They seem the same. https://www.amazon.com/gp/product/B07PWN832D/ or 3M SJ3560/CLR1333 Scotch SJ3560 Dual Lock 250 Reclosable Fastener: 1" x 10 ft, Clear: Adhesive Hook And Loop Strips: Amazon.com: Industrial & Scientific
I agree on the visible fastener thing. We tried bolted on the outside, set inside the slot, and using a 90" aluminum - which might work for you guys - and this look seems the cleanest to me.
On the Z-bar, for 3030, I'm using 3/4" height. I bought 1/2", 5/8", and 3/4" to test them all. 3/4" fit best with the Dual Lock on 3030. This is the one I'm using: McMaster-Carr
The good thing to the Z-bar is it bolts on the back of the rail. But sometimes that's the bad thing - not always possible. I think you might be able to go 90 bar on 1515.
If you go z-bar, here's the math (I think): 30mm is about 1-3/16" and goes flush; you're at 1-1/2" so I'd guess 3/16" to 1/4" less - or 1-1/8" would be right. So probably this one: McMaster-Carr (Here's the list of them from McMaster: McMaster-Carr)
But the other thing we tried - and are using on some panels - is just a 90 bar (like this: McMaster-Carr) and drilled the hole as close to the bar as possible. This worked fine with a piece of VHB to hold a panel on (we're using this for base-panels on cabinets since the Z-bar around the bottom wouldn't look as good). But you might be able to do that with 15-series with the Dual Lock and still be flush. I'd give that a try before going Z-bar on 1.5" rails.
FTR, part of the finished galley look is using these dust-cover things, which close all the slots with a plastic slide-in thing. I cringed at the $1 per foot at first... but it looks SO clean.
(Reminds me that I need to document all this in the build thread.)
