Years ago (2001) I used "super proguard" brand roofing material in my
'82 westy. It was not granulated and had a blue poly face and self
adhesive adhesive backing, and just under 1/8th inch thick. I put it
all over the interior walls and floor of the van, 3 layers. It went on
easy (summer) and held fast.... mostly.

The difference in road noise was noticeable.

But, and here is the proviso, be careful when you apply to the front
doors. My van had some wax on the interior surfaces of the doors and
the proguard did not adhere perfectly and started to droop in the heat
of summer and caught on the window.

Also, as i dismantle that van I can see where it really stuck and
where it didn't. The front doors, and above the driver/passenger were
drooping. Everywhere else was good.

I was happy overall with the result of using the stuff, no smell after
the first week, even in 40 C plus temps.

This time around with my '86 syncro I am going to try a different
approach, Will explain later.
