hi folks, i'd like to delete the ~100 trim holes on the exterior of my W123. the paint is already messed up and there is rust, so i'm not doing a concours style fix, just something that looks better than empty holes.

between bondo, hole plugs, brazing, TIG, etc., what is the most practical way to achieve a durable and smooth surface there?
