Mitch, When I refinished the bronze on my 68 coupe I used 3M press in place emblem adhesive product #08069. This stuff has worked very well and we have even greater temperture fluctuations here in Minnesota. The adhesive comes on a sheet with a double backing. Peel off one side and apply to the bronze, trim to fit, then just before installing the piece remove the second piece of backing. The adhesive is now applied to the metal. Press in place with even pressure. I would recommend using a soft cloth to press the bronze in place so that you don't cause any scratches. Thats it! No drips, no ooze and secure bronze. I did the entire job in my Crown Coupe with this stuff. It was designed to stick exterior emblems to cars. I found it at Napa and at auto body supply stores. Good luck!
