Boyd, 

Mine is polished and I put about 8,000 miles/year on mine with no problems. That includes some open road races and occasional track time.

So given that a polished aluminum surface is less efficient at transferring 
heat then an unpolished surface ( even if the difference is marginal) If 
one owns a Pantera and plans to use it for actual driving or in fact does 
use it for more then car shows and trailer queen status , what is the most 
effective way to make it "look good" without polishing it. (what cleaning 
method or cleaning products are the most effective?)

   So given that a polished aluminum surface is less efficient at
   transferring
   heat then an unpolished surface ( even if the difference is marginal)
   If
   one owns a Pantera and plans to use it for actual driving or in fact
   does
   use it for more then car shows and trailer queen status , what is the
   most
   effective way to make it "look good" without polishing it. (what
