Anyone ever used a rust converter? And do they work well? And I don't mean POR-15, that's not a converter

I've got some rust on my truck I want to tackle in the near future, and the converters seem like a nice, easy way to avoid cutting the stuff completely out of my bedsides, and fenders. If it works, of course.

So what is everyone's opinions, and suggestions on which brands to look at

 

I know a guy that swears by duplicolr rust fix. His cars are rust free

 

how does this stuff work? like how do you use it? i've got the extended cab ford rust and am looking at repairing here shortly to buy me some time before i take it to a body shop.

 

That's what I was thinking about using
Basically it creates a chemical reaction that turns rust back into a stable metal, and seals it all in one step

 

wow! thats awesome! so i could just cut out the loose stuff and sand it down to use it?

 

From what I gather, just wire brush all the loose rust off, then clean it up with rubbing alcohol or the like, and then spray/roll on the converter. And don't put it on paint, so it'd be all about going through the backside of the fenders so it bonds better.

 

why not on the paint?

 

It won't bond to the rust as well, it would have to get through the paint to get to the rust. If you concerned, just sand off the paint from the outside haha you got options man

 

yeah thats kinda what i was planning on doing. cutting as much bad out as i can, sanding down the next level and spraying this stuff on. i was gonna fill the hole then bondo it just to try and keep out as much moisture as possible lol hopefully buy me a year or so before i have to put new panels in

 

That's exactly what I'm looking to do on mine. Only with a rattle can paint job until I can do it up professional. But a rattle can with a lot of polish and clear coat to make it nice!
