Has anyone tried CT1? Saw a demo in a local factors it seemed pretty amazing! They say you can use it in wet & cold conditions, metal bar stuck to a brick & I couldn't smash it off! I'm waiting for warm sunny conditions (yeh right ) to stick my solar mounts on & am wondering if this might be the answer?
