There is so much truth to "doing something is better then doin nothing" ! My buddy and I always try to keep our trucks and anything metal in top shape even if what we do makes appearance suffer slightly. We believe it is better to try something than sit in the house and wonder what happened to everything that we ignored. LPS3, oil, cold galvanizing, rust o'leum, are just a few of tried and proven solutions with rust. High heat areas can prove challenging as not all products will be safe in high heat areas, common sense and research will prove worthwhile. There is a product called "Weld through Primer" that may prove helpful where heat is an issue, just a thought.
