I’m a little late to the party, but here’s what I would do in case you haven’t already found a fix!
Solution
It appears you have overlapping faces likely due to the array and curve modifiers that we used. You will likely have the modifiers applied already, but what you can do is delete a loop or two where the faces over lap, and try to merge loops that are close together (you may have to move some loops manually to merge them together).
If you are comfortable with “edge slides” by tapping the G key twice and welding vertices, instead of deleting loops you can try sliding some and welding. This will save you from having to re-unwrap.
Hopefully this gives you some options if you haven’t found a solution yet!
Cheers!
Chunck 🙂
