I had 6 items I wanted to get leaded today. I managed to get 2 of them done.
The opening of the EMS roll pan had a much more pronounced radius over the stock opening. I wanted to square them up on the sides to better match the stock opening. I also filled the low spots while I was at it. Hopefully these two areas are the most difficult and time consuming. The first thing that has to be done is grind the protective coating off the panel. The tinning butter won't stick to whatever it is that coats the panels to prevent rust. It is either galvanizing or aluminizing. Regardless, solder just turns brown if there is any left on the panel. After leading and paddling, it is difficult to file due to the taillight mounting area and the compound curves.
I still have the trunk lid, right lower cowl (more surface grinding to get the solder to stick), and both front fender tops.
