Cut the pipe 'downstream' of where you want the final cut. This should
hopefully give you enough spring in the pipe to get a pipeslice in to
cut it properly. I really really wouldn't try a hacksaw unless you have
room to make a second, third or fourth cut when the first one goes
wrong. Not buying a pipeslice, but having to get an emergency plumber
in, would be a false economy.

I always use plenty of Boss Green, but others will say you shouldn't. I
find the stuff works. Just have some kitchen roll handy, as it's messy.
