Thanks brian, a very interesting thread. As i said we generally use lanacote in swages cut with a grinder, this is about 85% of our work. (this is mostly cos i'm a 60kg weakling, and can't just use my weight on the falco's to get through the wire
).
I'm sure we're directed to use the lanacote over other substances, because of the extra cost and also the extra time for the clean up. Even a small splodge of lanacote on the end of the wire, most of it seems a to get squeezed out, so i guess if the lanacote's there then there's no air voids. We have never, as far as i know had a return on any swagework.
cheers
