Wow that looks terrible - however like you said its really only the blues.
I would trace out the areas you dont want to paint onto paper and then lay them down on the back before painting then add a larger 'cover' to block over the light blue when you shoot the darker blue. Of course a 'cover' to protect the new outer blue when painting the inner blue.
A nice thing about triple thick (before you do any painting) is after you apply it you can remover any latex applied over it latter on.
but not with oil based paint - something to think about
