RUST: what is everyone doing to prevent it?

[Doubletrouble]

 I've used a couple different brands of the so called rust conversion products in spray cans and so far I have not been overly impressed with them.

 Recently I did the bottom of the passenger door, it had some surface rust so I took a wire wheel to it on a drill to remove any loose stuff, the 2 coats of the "rust converter" and primer. The rust is showing through the primer already after about a month. Might be my fault since I didn't seal it with paint or clear over the primer though. Not sure.

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 ?
