HI,
Just to add my thoughts.
Mike NC is right about each point.
i have only done two headliners and i
kept my hours logged. it took 32 hours
to move a good headliner from one car
to another, install time only, with sunroof.
the none sunroof car was a new panel
and it took 19 hours. i watched that video
from 32minutes until they stopped showing
the install. that was scary. i work from back
to front with both cars and for the sunroof
car i finish the hole before i get to the front
windshield frame. i actually use wood clothes
pins and binder clips with blue masking tape
on the inside of each to protect from marks and
damage. i also use the tape on the headliner
as a guide line when the clips come off for gluing.
all the correct edge protection for the sunroof
must be in place to protect the white liner.
finally i have never seen anyone try to install the
long rails and the center panel together, that looks
like a nightmare. get the liner in and set for two days
then glue, then leave it for two days, then install the
inner roof panel then finally the body panel.
it can be done like Mike says clean hands and time.
just like the the nuns used to say to me;
Be patient or become one!!
