Just from going on the first link (links #2 and #3 don't work for me) - that rust on the wheel well is more cosmetic than structural. First, I'd find out how deep the rust has penetrated. If it is only surface rust, you should be able easily grind the corrosion away, treat the bare metal, repaint - and that should be it.

If the rust is extensive, there are a few options. Depends if you want the repair to last more than a year. Covering up the rust will only hide the problem, and usually, end up making it worse over time. Chemically treating the rust (most convert the rust - iron oxide - into something more chemically stable, like magnetite or some variant) - will be more effective, and most can be painted over. Takes more time and effort, prep wise, but the results will last much longer. The right way to do it is to remove all the rust and treat with a bare metal prep. This can be complicated, if the rust perforated the panel in question.

I'd highly recommend POR-15 products - http://www.por15.com/ We use this stuff on marine and auto applications, really does help with corrosion issues. If treated earlier, you'll have much less damage to deal with down the road.

Got my own related question on the topic:

What about buying new body pieces? I've got my own rust issues so I'm thinking of buying a new rocker panel section from 1stToyotaParts.com and having it welded in place. How feasible is that?

This one body shop didn't want to work on my rust because "they couldn't guarantee it."
Not that I wouldn't be willing to waive any guarantee ....

Good question - depends on how the body shop feels on welding on a new panel in that area. Some shops will not touch any repair if it comes close to a major body seam. If something is completely perforated by rust, the only way to "cure" it is to replace the panel itself. Personally, I've done similar repairs to old frame on body cars all the time - but never had to do it on a unitbody - yet. But the technique is basically the same in either case. Most of the time, a repair like that actually is stronger than the original piece (usually thicker replacement panel, additional bracing) - though that could be both good and bad.

Not true at all. I have saved many an aircraft component by treating the corrosion.

Refer to my post on the POR-15 thread for a detailed listing/directions on how to combat corrosion.

I have been dealing with corrosion for many years now and i have seen all forms of it, including magnesium, titanium, aluminum, steel, iron, brass, copper-berylium (nasty stuff there, cancerous too), copper, and any other alloy that i cant think of off the top of my head right now used on aircraft.

Corrosion is nasty business, its better to prevent the nasty by freshwater rinsing your car and spraying crucial components (bare metal, bushings, bearings, any moving part) with something like WD-40 or any other Corrosion preventative compound or oil based lubricant.

Oh-

Your Rust is all cosmetic, nothing structural.
