Can someone briefly tell me the best way to ensure a good slow down for further rusting of say the lower support member below the radiator and AC Condensor. My engine bay is empty and I want to treat these rusted areas with paint if possible. This member is quite rusty under the radiator. Stuff I currently have in stock is: DEM-KOTE RED OXIDE PRIMER / 70131F DEM-KOTE ENAMEL FINISH / 70112 RUSTOLEUM RUST REFORMER / 215634 LOCTITE SOLVO-RUST SUPER PENETRATING OIL / 81252 I find this rustoleum stuff isn't that great. I tested it on the rusted rear wheel hub baffle plates, and within a week rust was starting to show through the rust reformer coating alone. Tonight I scraped the member with wire brushes and jamming it with a big chisel to get the loose rust off, after first spraying it with the penetrant.
