I have always like the look of the F1's gold engine bay. my research found a number of solutions, may of the affordable ones were silver or aluminum. I was going to move forward with a silver one - at 20% the cost of the gold, however it required rivets to install, that was off putting.
A member on the britishspeed site linked me to the stuff i posted about in this thread. at 31$ a foot it is less the half the price of the AL stuff i was getting. and as an added value i am also getting the gold color - and it is easily installed with the adhesive backing.
