Not sure if this plastic will melt.

Not sure that is thin enough. The crack is very tight and a thinner liquid might penetrate better than a thicker adhesive.

Glue alone isn't going to do it, the force pushing it apart is enormous without some sort of reinforcement.

Do you have a recommendation for a mesh?

Yes. The dome comes apart and I can get access no problem. I used a orbital with 80 grit to scuff up the seam

I have a very tight angle on the inside. tape is going to be a PIA in that angle.
