When I had Tri-Y's on the fastback and torino I ceramic coated them and put the wrap on them still tended to heat the starter and it finally stopped doing it when I put an aluminum heat shield on it. Try going to a hardware store and looking for an aluminum sheet. Now if you really want it just to try quick and easy without buying anything else than a beer use the the can.
