[DeTomaso] 180 heat shield for deck lid

[Kirk Evans]

Jim,

If you haven't bought the aluminum yet, you can go much thinner to do what 
you need. I used a 40 thousands material as motor mount heat shields from 
the headers and light up cats on the AmeriSport GT5-S cars. The radiant heat 
was fairly intense and there have been no failures for 20 years. For the 
best result, you may want to use 2 thin layers with a heat blanket 
in-between. You can get a tremendous heat blanket which is used to shield 
flammable materials from copper pipe soldering from your local plumb shop. 
Should be lighter and far more than you'll ever need but would be the max 
paint protection. Good luck.
