I personally like the Evercoat line of putty and glazing..their two part polyester is excellent..super fine, quick to set, immediate sanding and no shrinkage..can be applied over season topcaots with a bit of prep...of course..I guess it depends mainly on what you are used to working with..

Hey guys, thanks for putting me on the right track, for some reason (stupidity I guess) I wasn't even thinking about glazing/spot putty to even things out. That should work better than bondo, these inperfections aren't that deep or noticeable. Thanks again

imperfections in body surfaces were fixed by application of lead at the factory.  Bondo or plastic body fillers replaced lead.  I would think a skim coat of filler to smooth worked areas would be better tha leaving the worked area uneven.  there are a lot of fillers on the market these day that work easier and give a better fininsh than bondo.  Also 3m has a deal the has filler ad hardener in a caulking gun deal, that you don't even need to mix.  You apply it directly to the repair area or to the squeege. and smooth it out then sand to your finish.

I am much more of a "wrench turner" than a body man and it has been decades since I decided to turn that kind of stuff over to more qualified people. So I may be totally off base here but I was under the impression that a thin glazing putty was appropriate for dealing with the minor imperfections left over from metal work that could not be dealt with by a few coats of primer/surfacer. In my mind bondo is for covering major gaffs. I suppose that a thin layer of bondo could be used as a glazing putty but then why do/did they make glazing putty?

I was looking thru "Skinned Knuckles" ads this morning..  I saw an ad for a company doing fenders, etc using no bondo.... On my Plymouth, 1929 model, the fenders and trunk deck both look like they were "rolled, or hammered" straight. I can still see the roll and hammer marks. Not bad, but noticable. They were painted over, there is "no" body filler on this car. I was planning on using a bit of "skim coat" bondo to hide these imperfections.  What do you guys use? or do you have the "rolled" "Hammered" look on your fenders and deck lids? and paint over it.  I noticed somebodys car on here that looked like it was painted over. Guess I am wondering if I am better off to leave it, or Bondo it?
Thanks,
Glenn
