Opened this can of worms today

[elroberds]

So I finally started to attack the rust today. I figured this would be the most important area to stary with. Good thing I have time on my hands. What seems to be the coating of choice on the inner fender wells once I get everything replaced, cleaned,converted, primed and painted?

Wow, that’s some formidable corrosion. I edited your question a tad. Are you asking what’s a good undercoating once you get to that step? If so, I sincerely admire your positive attitude.

3M makes some good products.

yep the first step before coatings is to replace the metal. It's a bit beyond spraying anything on it. Sorry, you've got serious work to do first.

I edited my question. Obviously, I have to replace metal, that much I do know. Not much else though. I was thinking about lizard skin or bed liner type products for the fender well. I have read many threads on it, just thought I would ask anyways.

Ahhh... the ol’ beehive in the inner fender
Wonder if it would be easier to cut that section of A-pillar out and graft in a more solid one from a donor/parts rig?

I used POR-15. Not in love with the product, but that is what I used. It is messy. The fumes will kill you, but it works as advertised.

I used regular automotive primers and paints on the exterior surface although I sandblasted my entire chassis. You'd be surprise how much damage you actually have that you can't see until it's blasted.

Internally, I sprayed a film of cavity wax to prevent future rust. I liked that the cavity wax remains flexible so if it gets scratched it'll heal itself. I was worried about some products trapping moisture under the surface of the material. I'm not sure what is really the best answer, but that's what I used.

Good donor Pig roofs / A pillars are hard to find.
If there is any rust on a pig, then there is rust at the bottom of the A pillar, just waiting to pop.
I have the same issues.
Replace the metal and POR-15 every place you can reach. Eastwood makes this:

I personally would not put bedliner anywhere that will see a lot of moisture, especially if it's likely to get beat on by flying rocks. In my experience when it chips water can enter and get trapped, causing rust and lifting.

If you are looking for an alternative to POR15 that you can brush on, check out the MasterSeries CT rust prevention paint. I bought some of this on the recommendation of another MUD member (@c2dfj45) and I'm really impressed with using it. I have a couple of quarts in the garage and use is to seal any internal cavity that I can get into with a brush. I have been creative and fastened a foam brush to broomstick handle in order to extend my reach into cavities Link below to their website.

[brisveganbj42]
