Unable to Thicken Surface

I am trying to help some students out with a fairing surface model. It is a pretty messy/sloppy model, but I have been able to thicken all but the most forward surface (Surface-Loft5 / Thicken3)). I had tried several things to try to smooth out the curvature, but nothing seems to work.

I am just trying to get it into Flow Simulation, so perfection is not necessary.

Any suggestions will be appreciated.
