I have another question: I have an old Toyota truck I use for going to the dump and hauling brush. It's starting to get pretty rusty. I am not worried about how it looks but don't want it to rust out.
There are two products I have seen at Walmart both near the spray paint aisle and near the garden area by the grills that is made just for that.
One is a spray that cleans rust/grease off and one is a spray paint to prevent further rusting and easy cleaning in future.
if not concerneed with looks and so far only have surface rust. go pick up some rustoleum spray paint and have at it. it will only cost a few dollars and will protect from rusting further.
Muriatic acid takes almost all rust off of metal extremely fast. But it also leaves the surface unprotected, which causes it to rust with a day or two if it is uncovered.
Ospho will remove rust and prepare eurface for painting. Then find a paint( -Rustolium etc) that will match to seal out rust.
I've tested a bunch of rust removers and converters and the best performer for rust conversion (by a LONG shot) is Duro Extend. I used to buy it at Home Depot but have been getting it cheaper at a local car parts place. It's the chemical of choice for Palomar Observatory, which is located in a high moisture environment plus winds which whip off paint.
Many years ago,I bought an old chest with metal corners that were rusted almost beyond help. I used Duro"s Extend, which at that time was a paint on. I couldn't believe how it turned out. Extend gave the metal a matt black finish and looked like new. A chest that I paid $30 for is now worth several hundred. Oh, and after all these years the metal still looks like new.
The easiest method is the rust converter will need two coats this is a primer so will need to do a top coat in enamel.The other option is the anti rust paint made by wattyl rust kill or hammerite anti rust paint i think it lasts up to 5years before rust starts to come though only preparation is to wire brush to remove loose rust it needs rust to adhere.These are tough paints and are durable only require 2 coats no top coat comes in various colors.
If you mean, protecting the backside from rust, go to a parts store and get some oily coating that can be sprayed on. It comes in "no drip" or "creeping" types. We can buy RUST CHECK formulas at CTC here in Canada. If you wish to make your own solution, disolve bee's wax (toilet seal rings) in Varsol until it is saturated then mix with old oil or used ATF.
Duro EXTEND By Loctite Corp., is the only answer. I used it on A VW Bunny P.U. to stop the rust bleeding out of the cab seam joint (between box & door) .Problem solved. I followed instructions and applied several coats but never did top coat with color paint, (just to see what would happen). Sold the truck 7 years later, with the black spots, but no further rust. I am a believer in EXTEND.
I have purchased a 67 Chevrolet Truck. It has been sitting for 17 years. I would like to remove the surface Rust and paint without a lot of sanding.
I don't mind sanding after I get most or all the rust and paint off. Again which Chemical is best for this & how much will it take to do a long bed pickup.
Where do I purchase the acid at & how much will I need for this job ? Here is the Truck I will be restoring.
Thank you so much I have heard about that product. But didn't know the name of it. Thank you. You have been very helpful and I appreciate it.

Can you remove or cover up rust from a car's wheel-well? I have an older car that has begun to rust just above one of the tires on the body of the car. I would love to hear any tips.

Go to your local auto parts store and ask for some Naval Jelly. You follow the directions on the bottle, but I think you put/paint the stuff on with the brush that is included in the bottle; it not only stops to rust but also removes it. Good Luck!
I learned this working for an auto body shop years ago. Let us know how you come out!
In short... Rust is cancer to a car and must be destroyed! Not covered up, or even encapsulated, though this can bide time it will be back with a vengeance! Get rid of it by grinding to bare metal or if necessary cut away enough metal from the body and replace it. Then use a water proof filler to reshape the work and finish with putty sanding smooth with 60-240 grit sand paper. Use finishing putty (which is only thick primer paint in a tube) and sand 400 grit paint and Clear Coat (important).
I have an 06 Toyota Tacoma that I recently bought a couple months back. Ater putting it on the lift and looking at the undercarriage I found a lot of rust everywhere on the whole undercarriage. Whoever had it before sprayed the whole undercarriage with a black rubber/Rhino lining material, because rust is everywhere! My question is, what can I do if anything to clean up some of it so I can at least keep the truck another year or so or how badly am I screwed? Thank you.

My husband has used Cocoa Cola to "etch" rust from tools before & once he used Sprite.
We a problem with the metal roof on our church, rust. Every few years we have the costly job of repainting it. We are thinking of using, Extend, but have some questions. Is Extend recommended for use on metal roofs that see direct sun all day? Can you paint over Extend with a lighter color? How many years can we expect Extend to hold up in this application, before rust shows up again? What is the square footage coverage per gallon and the cost of a gallon? And finally, how many coats of Extend will it take to do the job right?

Most likely the manufacturer has a phone number on the product. Call them, or your local hardware store that sells it could answer your questions.
