This job was interesting for a few reasons. They were in fairly rough shape, except for the smaller pieces of trim. Some of them had to be carefully soldered, as the copper plate has a high probability of blistering when it has prolonged contact with a torch. They were also quite porous, and some parts had to be stripped back to aluminum more than once. The porosity can cause solution to stick to the surface after rinse, resulting in the blisters. I did manage to get this job finished in a short time span.
