So if you epoxy over that, and you plan on making the car real nice, you will have to cut the lead and end up with the same bare lead.

So, if you check it and cut it down with 120 grit if needed. Then after epoxy you can level it out nice with a skim coat of polyester if need be.
I know what you mean Brian about the lead being to high on some factory seams, remember the thread about what kind of cars you have and I mentioned that I had a 72 Demon with the rear quarters being replaced and how whoever had done the replacement of the factory quarters didn't do a very good job because the paint was starting to blister. Ever since then it's been bothering me and I felt that even if I'm not going to do the repair right now, I should at least dig into it and stop whatever rust that was forming underneath the paint now so that when I took the time to repair it properly, I wouldn't have a bigger job than it needed to be.

As it turned out, I cut the paint down and it wasn't due to a bad repair job on the rear quarters (well the repair job was still bad but that wasn't the reason for the blistering on the sail panel). I'm thinking this car spent a lot of time on the track because the factory join at the C pillar to the roof was starting to let go (flex in the body from launching) and moisture was getting into the crack from water running down the chrome trim from the rear windshield. What I thought was all blistering, there was blistering but even after the paint was removed I held a straight edge up to the panel and found an excess of factory lead on the seam. This was the same on both sides...to much lead. I've got the driver's side cleaned up now but I'm not sure yet how I'm going to repair the quarters.

The guy that replaced the rear quarters did use the full factory quarter because he used the trunk gutter but cut the quarter about an inch from the door jamb and about 4 inches below the factory seem on the C pillar...why I don't know, why do I think it was used on the track? Because the inner wheel wells look as though they where trimmed to allow for a bigger rear tire and after I dug all of the gravel guard off of the inner tub where it mates up to the quarter, I found replacement metal to make the inner wheel well. I knew I had a bit of work ahead of me to make a nicer car but, this is one of those deals where paint can cover up a multitude of sins...not just the poor quarter installation but I'm sure in 72 the seam wouldn't have looked as bad as it does today and I know I'm going to need to remove lead to make a nice seam on the C pillar.
