Hello, The area under the rear bonnet grill has this metal frame. Mine has some paint chips and has rust as a result. Does anyone have suggestions to temporarily repair this, until I get it professionally done? I'm thinking I would need a heat resistant paint not just black touch up. Also, has anyone ever dismantled the rear grill and fin section to repair this problem? I noticed that there are rivets along the edges. Ultimately, I would like to get this powder coated, not the grill or fins (there anodized) but the frame, etc. Thanks for your help/input.
