Hi Cheveslakr, What body file do you use, on your panels? Do they come in difference sizes?
You would be hard pressed to find a better file then Pferd, unless you got a hold of some old Heller files
Martin tools also has flat and half round body files, don't know the OEM.
HJE has some files too, I have several of the curved files, plus it's an awesome mom and pop kinda store.
A few of my body files. I would go with a flat file and a half round file.

Coming from someone who has made a living doing collision and restoration, if the panel is not straight in filler it sure as hell aint gonna be straight in primer.
You don't rely on urethane primer to make the panel straight.
Body filler and polyester primers, ex slick sand, have far higher solids content then urethane primer, meaning shrinkage is less.
Wiping an entire panel is faster and cheaper(time wise) then spotting filler in several spots.
What I do is wipe the entire panel, come back with a 8" mud hog and 80 grit to knock the top off the filler. Wipe the entire panel with 3M or Mirka Dry guide coat. Grab my 21" or 36" AFS sander with 80 grit and block. Once the guide coat is gone, switch to 180 grit and reapply guide coat.
Once sanded with 180 grit, apply a glazing putty over entire panel. Glazing putty is basically a thinned out version of body filler, spreads easier, sands easier.
IMO, if your filler is thicker then 1/16 you need better metal straightening skills.
Plus, straightening metal is faster and easier then sanding filler. These cars have darn near complete backside access, no reason why one can't get a hammer and dolly into most places to correct damage.
The best filler I ever used was Marson Platinum Gold, but 3M bought out Marson, I believe its now the same product.
