I would be interested in painting my poptop White but I am afraid it
might look funny on my Burgundy Westy. Has anybody done this and have a
picture that they could share? As far as touching a surface to make a
determination of how well a paint is preventing hear transfer, this
seems valid to me. Conductive Heat Transfer calculations look at the
temperature differential.....if the exterior surface temperature is
lowered the differential from the outside temp to the inside temp will
be reduced, the time required for  the interior to get hot will be
increased. I like the idea of placing a Space Blanket over the Poptop as
this would preventive heat transfer that occurs as a result of
radiation. I also believe that an exhaust fan at the roof vent connected
to the auxiliary battery would have to help keep the interior
temperature lower....I may have to perform an experiment some weekend
while my Westy sits and bakes in my driveway.
