While I ended up using Dow Corning 795 as my sealant, I had originally purchased a bunch of Sikaflex 295 UV and primer to use for the windows. After more research, the Dow 795 was the dominant recommended product, plus it was about 1/3 of the cost of the Sika 295. I returned all of my Sika for a big refund, but I had already opened the $75 can of primer to use on the hatches. The articles above recommend that you paint the acrylic on the edges that will overlap so to create a uniform, black coating. The biggest weakness I found in this fastener-less method was that the bond is only as good as the paint on the hull or the acrylic. To overcome this, I used the Sika primer on the acrylic because it etches on chemically and creates a very permanent bond better than any paint. I let the primer dry completely, then gave it a very good sanding to ensure good adhesion with the Dow 795. I think this stuff will be much, much stronger than any paint I could use.
