For surface rust, you could seriously slow it down by wire-wheeling it off, coating with rust converter, and spraying some kind of heavily resistant top coat. But I see some areas you will want to grind out. You could do the "wire-wheel and coat" method all over, but you will just be covering it up. Not really repairing it. In order to really STOP the rust, you have to remove it all down to bare metal.

There are products that seal the rust and ends rust when applied. You don't need to do anything but spray it on the rusted surface.

Name the products as I might buy some

FYI plastidip can be used as a undercoat after you fix the rust. I would seal it with proper chemicals first though of course. But the plastidip will keep salt off the metal. Plus you can peel it off and recoat it very very cheaply later!

There is no magic cure for rust. All these sprays and coatings use the words "encapsulate" or "convert", not "remove" or "cure". They don't stop rust they slow it down or (most often) stop it from rusting on the surface. Underneath the chemical reaction is still occurring and eating away the metal.

There's nothing wrong with using those products on areas with some surface rust. They can help slow the spread of rust to other areas while repelling water and oxygen. But there is no quick fix for rust that has penetrated the surface. The only option is to remove the rust and expose bare metal, then treat/coat the metal with a rust resistant paint (such as Rustoleum).

There's a reason they call it "Cancer". You have to cut it all out or it will spread.

Stopping major rust is usually very difficult and that's why no one likes dealing with it. As mentioned, you'll never stop it by just spraying a coat of anything on it. I recommend sand blasting, cutting and welding wherever necessary and finishing it off with a coating like POR15. That's a lot of work, but if you go through that process, depending on how good of a job you do, you'll probably have it under control to a point where you won't really need to worry about it anymore if you take care of the car. Keep in mind wherever you weld on the car, the opposite side of the metal you're welding to has factory sealer on it. That sealer will be burned off from a good weld, exposing metal, which in time will rust if you're unable to get to that surface and re-coat it after welding (ex. the inside of a frame rail). It's a catch-22 situation, you give and take, it's tough to win.

I use rustoleum hammered to cover rusty surfaces. All you have to do is brush off all the loose rust and paint right over it. The finish seems more durable than the regular rustoleum paint. Having said that, the only way to stop rust is to remove it completely, either sanding/wire brushing down to bare metal or cutting out and re-welding in new metal.

Thanks for the responses guys but im still a little lost,
yes i understand i have to remove the loose rust , but
i was planning on removing the loose rust to bare metal with a wire wheel
then apply the walmart rust stuff , then put coats of that bedliner from rustoelum

will this be effective at preventing it

This approach will probably buy you, one, maybe two years before seeing new rust bubbles popping back up.

If you aren't able to sandblast and cut/weld, or if you just don't want to... My advice is to remove as much of the rust as possible with your method of choice and then use POR15 on it. After you've used that, then consider something along the lines of a bedliner coating. Wire wheel for odd corners and a Roloc for more open flat areas. It's expensive, but it's what will give you the best results.

It all depends on the amount of rust you have. Surface rust can be taken care of easily just by removing it and using the spray can stuff to prevent it for the time being. Once the rust starts to eat away at the metal there is no easy fix. When you remove the rust if the metal is even pitted a little bit the rust will return. Sometimes it will be a year or two or sometimes it will only take a month. You can do what you were planning on but i wouldn't count on it lasting long.

Living in maine, we get rust too.
Wire wheel and die grinders are your best friends.
Take as much as possible down to bare metal, use rustoleum primer, undercoat, and coat it with oil in the fall.
Coating it with oil will let dust an crap adhere to it, kind of like a wax coating.
You can rinse it off in the fall.

Salt and stuff wont stick to it, its never failed me.

I'd use POR15 if you can afford it.

 

[sickasssteve]

try to knock as much as that shit out wire brush sand paper wire wheel grinder but be carefull it might not be as thick as u think but i deffently say put some por15 on it to prevent it from comeing back

 

[gst noob]

I media blasted my under body and used por15 on the metal works great! That stuff is the best for preventing rust also painted under my carpet with por15.

This by far is the best rust "stopper" i have ever seen... it can be painted on or sprayed on... and it actually works...

 

[DSMbabyy]

por15.

EPIC! get this stuff. brush it on or spray it... wont stick to painted surfaces just bare metal.... awesome stuff done deal

Chassis Saver is the same thing as POR15 only cheaper. We sell it at my workplace; it's about the same price as enamel paint and you don't need primer. Comes in gloss black, satin black, and silver (silver is overpaintable). Remove loose scale, and brush it on. Doesn't get any simpler.
