I planned on using some rust preventative rustoleum on the underbody on my honda accord. Around here, the state uses salt on the roads which really rusts the metal underneath. I was wondering since the weather is getting nicer, if someone could let me know what parts underneath that I could spray, and which ones I couldn't. Thanks guys.

 

Just ensure that you power wash the salts and chemicals off the bottom and you're good.

No real reason to coat the bottom with that stuff.
