undercoating - reply

[John Hertog <crossram@xxxx>]

Hi Ben,

I also agree with Don. Leave as much of the original undercoating in place.
Whatever areas need to be filled in, use roofing tar, that plastic stuff...
available in hardware stores. Lay it in place with a putty knife, allow to
set up a little bit, and then use a Scotch-Brite pad to give the correct
texture by tapping the pad against the roofing stuff... it really works.
