Anyone who has assembled a NexDome has noticed tje inherent thumping, as the dome turns over the walls. In some cases the dome sections are NOT level with each other and this presents a more profound problem. This can cause the dome to stall or stick which can effect the dome rotation kit to jump the track or grind the gear.
Several have mentioned filling the space so I did. I used a modeling clay and filled the spaces between the dome sections. In a few areas I added material to level out a few of the uneven transitions.
It worked for exactly 2 days. First the added leveling material fell out as the dome ran over the wheels. Even after the clay fell out the dome was much quieter and ran smoother with the spaces being filled. The dome also didn't thump, stick or stall. The next time I was in the dome, all but a few, of the clay remaining in the spaces fell out. Other than cleaning up the clay the dome is no worse for wear.
I wanted to use a material that could be removed easily, in case of having to remove the dome for any number of reasons. I did not sand or otherwise rough up the area and I'm thinking that might be required.
If anyone has tackled this please post here.
I will keep reporting back as I try other materials or techniques.

So it has been awhile since I worked on controlling the thump thump thump of the dome while rotating. I ended up using gorilla tap, found it in white, in ~4" strips between the sections of the dome making sure it was stretched tight. I have to say the thumping has been reduced by at least 70% and the wheels no longer get trapped where there is an offset to each section. It has held up well over the summer, and it has been setting record highs, and appears to be my solution.
