Aint sure where to put this subject but I see that this forum is perty popular.
Anyways I have a 99 F-150 with 59000mi . I am getting some serious rust coloring on the underside. I do use the truck at the Outer Banks bout 25-30 days a year. When I get back to the house the truck gets a good wash down, I think. Actually I only know one person that cleans a truk better than I. But then theres you guys that don't drive your truck when it rains! Glad I don't know you personally.
My question is how to stop the rust? I've heard of Zbart but can you get this with the discoloration already?
I did a search on this and aint found an answer . Sounds like folks have it done when they buy there truck new.
Please let me know what you would do. I don't see me keepin this truck more than 2 or 3 years maybe less. Would like to trade up to F-250 and maybe deisel! Girlfriend keeps talkn a new house Now that I think bout it she is getting some miles, might trade her too!! Thanks for any input.

 

You could use a product called Por-15, it's expensive, about $100 a quart, but it will stop rust in it's tracks. It's good stuff, maybe even a better investment that a house After my truck gets painted i plan on doing the frame and the inside of the body panels with it. I have friends that used it on there classic cars and they haven't said anything bad about it.

There is a spray you can get at Wal-Mart called Rust Converting Spray. I used this once on a VW Beetle floorboard and it really works well. It bonds with rust and changes it to an oxide stopping any progression. The converted rust becomes a seal agains future rust. Then you can have the whole thing undercoated. I replaced one of the floorboards because it rusted thru. The other I used this product. The new floorboard rusted and the old one remained rust free.

 

Don't know how big the patch is, or how far along it is, but this works. Find an old toothbrush and some flouride toothpaste. Get to scrubbing with that toothbrush, and you will remove all surface rust (doesn't work for pitting, or bad rust). This trick has worked for my off-road lights, as they developed rust on them this summer after my family neglected to take care of my truck while I was away. You'd really be suprised at the results. It's also something that everyone (I hope) should have. The only thing is, my Dad started to get suspicious when his toothpaste kept ending up in my detailing kit.

That POR15 - Where can I find this? How do you apply it? Is it something you can spray on. Also does it have a color to cover the rust color, thats what hurts when I look at the frame and its turning orange.
