I'm confused.

How does the foil help to protect the bricks from outside influence?

I have to concur with Steve about pressing. Before getting deep into this forum, I made the mistake of taking the iron to one of my tanks. It's in bad shape. I'm dreaming of a shaped 3D pressing surface. It has flat clamps that pull pleats straight and even so you can press a kilt as easily as ironing a shirt. Anybody got a free time to make one?
