Ya
I talked about this in this thread a few pages back.
Lars is saying to fill the crack on each side of longeron with glue.
So I did
Looks terrible untill you put heat on it, heat mostly fixes it.
But why?
Adds alot of uneeded weight
Looks bad
Harder than hell to get off for repair
Adds time to build

Just my opinion - dont do it

Use tape- masking tape, duct tape, caulking, whatever, but dont put glue in there, its like he wants to sell more glue...

I put glue down by the longerons also. Mine looks bad too. Lars says without it, grit will get down there and that grit will telegraph through and be visible from the outside. I don't think it adds much weight, maybe a couple of ounces, but I would not do it next time because it looks bad. Maybe I would do it, but go very lightly with it. Maybe use a syringe with a very small needle so it lays down a very small bead, exactly where you want it.

Could we apply glue to the inside after covering, and add a strip of tape to seal the area off?

So what is the accepted method of finish tape on the vertical stab? 4” tape wrapped around or 2” tape on the side with overlap?

I used 3” if I remember right
The wider it is the harder it is to do the curve to vert.
I ended up cutting and matching the end.

I watched Lars’ video on how to do it, you have to use alot of heat and extra hands, even then its hard to make the edges smooth.

As for the overlap - I cheated the tape to one side a little.

The next time I will run a 2” tape on the overlap side first - then wider tape over the top to make it look even

Oratex gotta better of me today. Attempted the transition to vert stab. Tried it per Lars instructions-twice. No joy. Gave up and decided to do it in sections. Problem is there is a buildup of activated glue and it looks like crap under the tape. What can I use to smooth out the glue before another attempt?

If you are talking about pulling the fabric off and trying again? The only thing I found to work was sandpaper. You've pretty much got to remove all the old glue and then re-apply for it to be smooth. If you are talking about re-applying finishing tape over glue that has been activated? This works for removing dried activated glue...

YMMV,

Seems like sanding rubber. What grit did you use?

Razor blade will work with a little heat

OR

More glue, use it to smooth it out

I don't recall exactly. Whatever works? Start with 100 grit. It's a lot of work to get it smooth again...
