I'll have to dig that wax out and remember to bring it with me... if I can find it.
Tonight I got the last bits of blue tape off of the front by the street side riblet. I may have mentioned this before, but I have learned that it is much much easier to hold the tape back a bit when applying it, say from 1/16 to 1/8 inch, and never risk having it get under or into the glue joint. It is far easier to wipe the excess glue so that it does not get caught up in the squeeze out, or pinched under the edges that way, and the result is actually cleaner than scratching away at the blue, or worse, having some tape stuck in the joint that just can't be fully removed.
I had a couple of small areas like that, and I was a little concerned about them, but then I realized that I was 12 inches away with my head lamp on.

When I stood back and looked thru the curb side doorway in the ambient light I realized that I was picking nits. The next time I am laying down some poly, just a little lick with the hobby brush in the corner to seal the little scratches up and all will be good.
Right… now on to the roof. The inner ceiling panel (including the front wall) comes first, but before I join the three panels together (front wall, front radius with front ceiling, and main ceiling) I want to make the cut out for the front storage locker in the front wall panel; and since I have decided to divorce the tongue box (TB) from the locker and front wall, I need to redesign both the locker and the box.
So I dragged the original prefabbed parts for the locker out, then played with and stared at them for an hour or so trying to “see” the changes needed. Attempted a couple of hand sketches, even had a go at laying out my thoughts directly on the parts, but it seemed like a waste of time compared to being able to do it properly in the 3D model the next chance I get. (I probably should have stayed after work and done that instead.) Anyway, my original design for the locker was pretty crude, with simple joinery, and no provision for trimming the edges of the wall ply at the cut in, so I will take this opportunity to improve the design in a few areas. I’ll rabbet the outside edges of the locker opening so that it forms a hard edge around the cut in; and the area that would have been the back of the TB under the locker will need to be cut shorter. I’ll lose some volume to the extra panel separating the two areas and the gap between them. Also, the locker sticks out of the front wall a few inches, and the mounts welded to the tongue for the TB are only 5-1/2 inches in front of the wall, so I’ll probably have to step the TB under the locker, being careful not to create a trap for debris or water; and it has to look good, too!
So even though I didn’t get much physical work done, you have to go from point ‘A’ thru point ‘B’ to get to point ‘C’.
