falling headliner datapoint

[LOACESQ@aol.com]

Hi List,

IME, the biggest problem with trying to re-secure the headliner is not that
the old foam bits get in the way, but rather that the heat absorbed by the
roof during hot summer days loosens most adhesives.  The 3M products (like
Super 77) cannot take the heat.  Use a high temp contact cement.  I prefer
liquid cement applied with a foam brush, which allows me to get greater
saturation and greater precision.   If you want a spray, JC Whitney sells a
high-temp spray called Heat Shield Contact Cement for $10 a can. 

With all the old foam debris on there (it's impossible to clean off), you need
to saturate to achieve good adhesion.   To reduce bleed through, allow the
cement to dry a bit before pressing the cloth on.

Using a foam layer is another way to avoid bleed through and the foam covers
the debris bumps as well, restoring a smooth appearance.  Apply a heavy layer
of cement between the foam and the headliner backing board.  With the foam
providing insulation against the most severe heat coming from the metal roof,
you can then apply a light layer of cement between the foam and the interior
cloth headliner, light enough not to bleed through.  While the advantages are
apparent, the problem with using a foam layer is in finding a high quality,
temperature resistant foam.
