I just used jb weld on a headlight on my tractor but I'm sure they have a glaze putty for that.

Be sure that you get the rust out from way down in the bottom of those pits.

Get all of the rust out of the pits, and then, yes, Bondo works quite well. I've smoothed out a couple of Farmall hoods using that method.

whatever you use to fill it - sandblast first, then spray with phosphoric acid - that'll convert any remaining rust to something benign.

Hit it quickly with a wire brush, then fill it - prime it - paint it.

Depends on how deep your pitting is. Clean out all rust and use multiple coats of High Build or Filler Primer with sanding between coats.

Last winter I used a filler that had aluminum in it to smooth a couple of fenders that were pitted so bad some of the pits had small holes rusted through to the other side. The fenders were sand blasted before I got hold of them. I forget the name of the stuff but I got it at a local auto parts place. It's a little tough to work with because it starts curing in a minute so you have to get it spread fast. After sanding I used a final thin coat of regular bondo. The job came out really nice. I have a notion this aluminum stuff will flex more without cracking when layered thick. Jim
