Here's how the spire looked as the stripper "dwelled". It may not look pretty, but it makes short work out of getting down to bare concrete, and it doesn't hurt the concrete at all...We let it sit for a few hours. Malik, who'd been with us all morning, went home, leaving just Norbu and I. So almost no pictures of the dramatic process of removing this stuff! I was on belay all evening, didn't want to risk using the camera...Norbu might fall...
