A few months ago i was working on an old Ford Galaxie 500 and ran into a little problem with the lead on it. Normally they have got my working on newer cars so i've had few run ins with it. Basicly i stripped the whole thing down with 36 then 80 on a hog. I was using some Evercoat Glaze on a leaded seam over the lead that was sanded with 80. i started cutting it with 80 and when i was just about ready to 180 it i started noticing some of the filler was actually coming off the lead at the edges making it impossible to feather. i ended up using some ppg epoxy and then fixed all the leaded seams and then primed.
is this what you always have to do to lead or was i just unlucky?
