Undercarriage rust

My 03 wj has light surface rust on almost every part of the undercarriage, axles, driveshaft, exhaust, practically every thing under the vehicle. I did some poking and prodding and there is no serious damage, at worst some light flaking, but would wire brushing it off help? I don't have the money to do a full on undercoating. So should I leave it as is, brush it, or brush and rattle can undercoat it?

A few times a year I get under my jeep and cover any exposed metal with spray paint. Yours doesn't seem to be an issue. I would scrape of the loose stuff clean good and hit it with some rustoleum and regularly check to make sure you keep the exposed metal covered.

What you might do depends greatly on where you drive. If the highway department uses salt to melt snow and ice on the roads, you need to monitor and deal with the rust. If you drive anywhere else, it will be fine, just like it is.

Yeah it's definitely not that bad. I'll clean it up and hit with some rustoleum. Should I avoid parts that get hot or can regular spray paint handle the heat?

Wet or dry, paint burns.
