I’m the FNG to all this, but I really need some help. My car is a 1966 Nova HT with 350cu. in. and 350 TH. I recently installed a front disc kit from SSBC. While working on the rear axle, new shoes, drums and wheel cylinders. I found one of the backing plates with a broken lock washer, so I pulled off both plates and bead blasted both to knock off rust and paint. The question is what can I put on the backing plates to control rust and give me a good look? They are down to bare metal so I think that limits my options but I’m sure one of you gear heads have the answer to my small problem.
