Interesting. How are the tops of the mounts sealed? Those slots may be difficult to cover.
It looks a lot like how yours is mounted -there is a just a bolt hole as opposed to a slot like in the prinsu (which I hate). The single hole (vs a slot) is easy to seal. On top is a rubber washer, aluminum washer, and then bolt. I'll be swapping the rubber washer out with a red silicone washer.
I think I might put down a good layer of butyl rubber on top of the entire washer/bolt assembly and then cover with a nicely cut piece of either vapor barrier or some form of black plastic to mate to the butyl rubber so that it doesn't get gunked up with dirty and debris.
I've attached a pic of the RA mount and the prinsu for comparison. You can tell the person that installed the prinsu in the pic used a butt-load of silicone.
