[RE-wrenches] Working on metal roofs.

Sun May 8 11:11:31 PDT 2011

Caution on the Coke & Pepsi - They contain pantheonic [sp]
acid it will hurt a metal roof. If applied to your truck or
car paint finish it will do serious damage  in short order.
The pantheonic acid is what gives your mouth that "clean "
feel, as in grunge remover. It can and will dissolve denture
material overnight.

Check for the ingredients contained therein.

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
