Being a 2nd gen owner and living in Northwest Ohio I have some rust on my truck. Most do around here. I have been reading, searching and reading some more about rust prevention. I have some rust on my '01 3500 that will get repaired/replaced with new metal but I am curious to see what everyone on the site here is doing to prevent this vehicle eating monster from getting their truck.

 I have read that an oil based undercoating that is applied annually seems to work pretty well. It would have to be included in your maintenance program in the fall for winter preparation but has been pretty effective. There is also a DIY variant that could be done at home with used motor oil and diesel fuel mixed 50/50 and a hand pump sprayer.

 I have not tried this yet but I am giving it a lot of thought. 

 I'd like to hear from others on the site to see what their rust preventative measures are. Not looking to start a debate about EPA approved this or that, just what works for you and no judgement on your regiment. 

 Thanks

You would think by now there'll be a product cheap and readily available in a spray can or something, that neutralizes rust and keeps it from spreading. I know there are few products out there, but they must all suck or we would all know and use them. 

 

There's several paint on rust converters here, is it phosphoric acid or someat but can't remember the name, turns rust black and kills it, must have it there ?

Yeah we have it, I tried it but later on it was still rusting. Best I found is to cut it out, sand blast, weld, recoat and don't use it in winter

Or when it's raining, foggy, humid or anything inbetween.  Death Valley it is then. On the subject of rust and cars in the late 70's early 80's here car makers had a glut of new cars they couldn't sell, one in particular Britsh Leyland bought a huge amount of land to store 1000s of car on, not far from the coast and on grass which of course grew faster than cars were sold, these cars absolutely rusted while you watched and every model is as rare as hens teeth none are worth anything as all were dogsh.. anyway i'm sure one model called a metro there are 14 left with only 5 on the road. BL went bust BTW ?
