Must I re-anodize after sanding and polishing aluminum?

I have some aluminum automotive trim that I have repaired, fine sanded and polished.

Is there any way, short of having the piece re-anodized, to protect the finish from corrosion?

You could lacquer coat it, but it would not match anodizing in corrosion resistance.
