What should I do about this?

[farmerjon]

I have rust all over my rig, though most of it is not too bad, and a lot of it is under the truck on the frame. In the spring, I plan to get under there and just sand, sand, and sand some more, then either POR-15 it or Rustoleum it.

But, this spot is right next to my rear passenger side tire, and everything the tire picks up is thrown at this spot. So I want to deal with this right away...

What is recommended to do here? Should I just tape off the area and spray it down with Rustoleum? Notice in the photos below that it is in two layers, as in, there is a layer of air in between...

Thanks for any input or advice you can give. I really want to keep this rig forever. Cheers.

really needs to be eliminated. cut/grind back the rust as far as you can then fill it with bondo or similar, or cover it with a nicely shaped metal plate, tape off and paint it up. either way, its going to look like a repair, which wouldnt bother me. i think prepping to bare metal, filling, then painting would be the easiest way.

Theres guaranteed more rust a few inches beyond that. Wire wheel that shiet, and as WMW said: bondo and paint will do you good. Be sure to get all the rust out though otherwise you're work will have been a waste.

Try cutting it out and install some SR5 fender flares to hide it.

That's not a bad idea Drcoffee, except I really want to deal with it,and it will just rust again.

Thanks WMW and blizz86 - I think I will try sanding it/grinding it lightly and then applying some Fluid Film since it seems to penatrate. I've bought a little bit and will test it out on this spot... I'll spray it up in there and see what happens.

I really HATE RUST!

Farmerjon, I would do like WMW said. Do some grinding and sanding to get rid of the majority of the rust. You could apply rust converter as well once you get the majority of it sanded off. It chemically converts the rust and hardens it. Then do your bondo, followed by primer/paint. I would do that and then get the SR5 flares like I have, or use something else to cover it, like a few layers of clear vinly, or por15, herculiner, etc. Something that will not not rust.

Hope this helps some!

Well I had that problem. Too big of a hassle for me to deal with and I wanted it to be done right, so I went to a shop. They cut it out and then replaced it with new metal. I then painted it up and its as good as new!

I thought about that... how expensive was it? Can they color match the paint?

I've also thought about just having them treat all the rust on the undercarriage while they are at it.

Though it would be very expensive, and I don't have much money for this, I feel it would be done right and they could do it much easier than I could.

Thanks man, appreciate you chiming in as well. I will probably go this route in the long run, not sure if I can do it right now with the snow and cold weather right now. Might just coat it with something like the aforementioned Fluid Film until I can really attack it. Now that I'm in a MUCH dryer climate, I'm hoping I won't have to fight the rust as much after I treat things.

I would do it right the first time. If that means taking it to a shop, then that's what I would do. Shop around. Should be fairly cheap and you could probably blend the white in yourself.

How does that work? Do I find the color code for my "Natural White" and buy a can? Or?

yep natural white from duplicolor works perfectly, i have a few surface rust spots on my roof. I sanded it down to about 800 grit and gave a few light mists of this

i still need to wetsand it and polish it out, but it matches great

There ya go. Though, if SEM sells it, I would get it from them as it is polyurethane. Dupli colors paint is acrylic, and the SEM is going to be 10 X stronger and more durable. That being the case youll pay about 3 X more for it.
