Also, I have been thinking of the best or easiest way to make something to
cover up the ugly opens on both sides of the KR2 wing joints or attachment
area? Of course, without using tapes or anything hard to remove...?!

Other than following the plans for critical structure and systems, try
not to over think building a KR. For example, the area listed above.
When it came to that point in my building , a dozen years or so, I just
wanted to get the KR in the air. I laid up fiberglass strips to cover
the wing attach gap but didn't like the way the turned out. I put them
in the trash and went to the hardware store and purchased a roll of
aluminum roof flashing. I cut it down the middle giving me two 3 inch
strips. I put one strip on each wing and attached with 4 small #4
screws on the top and maybe an equal number on the bottom. 700+ hours
later with remove and replace each year and they are still like the day
I applied them. Well, maybe a bit worse for ware but not to the point I
need to replace them. The gap does need to be covered to eliminate drag
but just cover them and go fly. A photo shows the covers and the 4
small screws that secure them to the top of the wing. They have
survived 200 mph on at least one occasion.
