Default Centuri Fin Overbite

I restarted a long-delayed build of a Semroc Centaur. This is a reissue of an old Centuri kit.

I ran into a problem that's plagued me with a lot of Centuri designs. The double-swept fins are made of two parts, allowing a sharply angled leading edge. I round the fin edges first, then assemble them.

Despite taking care to keep things even, I ended up with the situation shown in the attached photo. There's a kind of overbite or underbite.

Any suggestions for how to even things up? I'd rather build up than sand down.

Lots of putty? Tissue wraps?
