Sorry to be downer here, but I see a couple of issues.
One, I would absolutely not use gorilla tape on the edges. You want a harder surface butting up to your tubes. With gorilla tape, it'll grab grit and act as sandpaper to your tubes.
Two, if you are going to varnish the bottom, why not run it over the edges and up onto the top. tape off a buffer of maybe an inch or so from the edges and varnish the tops and sides all at once. Use one of those little small diameter rollers -it's easy as pie.
three - if your are going to spar the bottom (and maybe sides?) then why not spar the hole thing? Put 4 or 5 coats of varnish on top and sides, 2 or 3 on the bottom, then comeback and tape off the perimeter as described above. Put a heavy coat of varnish on the top, then sprinkle with grit and reroll. Mix in more grit if needed or dribble a little more varnish - you'll see what I mean when your doing it.
I've not seen good long term results with the spray on liner... it usually chips and flakes off and in my experience having a good fine grit is better than a coarser texture. In either case, you'll end up tracking mud into the boat, the coarser the texture the harder it is to get the mud out. Mud means invasive potential. In my experience, finer grit is better anyways - in either case if it gets too thick just bring a bucket and wash off the floor occasionally. It doesn't seem like I do that any less with coarse gription on the floor.
I guess in the end what I'm saying is keep it simple, varnish works great all the way around, it won't wear on your tubes on the corners and it'll be easier to clean and refinish down the road.
PM me if you'd like to chat, I've done this many times with numerous boats. KISS - keep it simple...
