They allege that it does help, but they also say that you should use 
Extremeliner on top of it for real heat protection.  Which tells me to 
keep on looking.

This sounds like a good, low-cost option.  But surely by now (cars have 
been around for about a century) the major auto manufacturers have 
settled on something good and cheap for new cars, which is designed to 
be in the engine compartment.  Of course, retrofitting it to a Scout 
might be a problem.

Noise don't bother me - I just turn up the radio.  As an added bonus, 
between the truck noise and the radio most customers don't engage me in 
overly long conversations.  But still, it wouldn't hurt to reduce the 
noise a bit, and if it helps with the heat, so much the better.  So, 
maybe it'd still be worth a shot.
