"You're supposed to dump the bucket of stuff in. Then clean the area thoroughly around the leak."

"With what?" asked Major Winship.

"Sandpaper, I guess."

"With sandpaper?" Major Winship said, emptying the bucket of fluid into the drum. "We don't have any sandpaper."

"It's been a long day," Capt. Wilkins said.

"Mix it thoroughly," Lt. Chandler mused. "I guess that means let it mix for about ten minutes or so. Then you apply it. It sets for service in just a little bit, Finogenov said. An hour or so, maybe."

"I hope this doesn't set on exposure to air."

"No," Capt. Lawler said. "It sets by some kind of chemical action. General Finogenov wasn't sure of the English name for it. Some kind of plastic."

"Let's come back to how we're going to clean around the leak," Major Winship said.
