[RE-wrenches] Working on metal roofs.

[Kirpal Khalsa]

While most of these safety methods are crucial, another trick to use
inconjunction is to spray the roof with some type if sodalike coke or pepsi
so when it dries the surface becomes tacky and sticky....really helps with
mobility especially while manoeuvring around....l
Another good help is the harnesses which haveloops in front instead of just
in back...Petzl makes some nice ones but they are expensive...
Good luck
