Gosh could one seriously expect to even FIND, much less afford, a "filler free" fender repair man?
Certainly not someone able to restore the average original fenders we commonly find with bead breaks & farmer welds...not without some filler.
It think it's time for people to know & accept the simple facts...after you weld and repair a metal panel it's gonna have a certain amount of
A) Lead
B) Body filler
C) or high solids primer...(spray-on body filler)
I realize this is getting off the track of the original posting as he's just asking for a bodyman at this point. Hopefully he'll find a suitable candidate, put the terms & anticipated costs to paper and stay in constant communication as the job progresses. Hidden costs WILL arise and one should agree beforehand how these hidden costs will be handled in order that everybody stays happy.
Also I would suggest the Model A owner fronts as little payment as possible, until the job is finished. This practice will offset the "burnout" most bodymen experience near the end of a long project...keep the carrot dangling...don't get trapped with a half finished car and a broke bodyman who owes you work but has a "better" job in the next bay.
I've watched many a restoration/messtoration end in grief & lost friendships
...all unneccessary with some firm ground rules and that dangling carrot

Best of luck
