Reddit reviews 3M 03584 Professional Grade Rubberized Undercoating, Corrosion, Water and Salt Spray Resistant, 16 oz, 1 aerosol

You think something like this would work similarly even though it isn’t necessarily “commercial grade”?

1. PO is an idiot. Definitely restore the factory harness. It's a lot of work but you'll thank yourself when you replace/upgrade the radio in the future.
   
   
2. High-pinion Dana 30 from late 90's XJs. Make sure that the gear ratio is the same as your old one.
   
   
3. It is bad tires. It's also bad shocks and bad alignment.
   
   
4. I didn't have the patience for POR 15 so I used 3M undercoating spray. It's basically similar stuff to what the factory used. I used 4 cans to really get everywhere and I'm very happy with it.

In your other post, its hard to tell for sure but the factory paint looks to be in tact. If you have them plastic wheel well liners are the first and most effective line of defense to stop rocks from ruining your paint.

I wouldn't sand off the factory paint just so I could apply POR15. Also I don't think you can get the paint out of the nooks and crannies without a sandblaster. POR15 says right on their website you CAN apply it over existing paint, but you don't get the anti-rust benefits unless its applied over bare metal. If you are going to this much trouble, you really should wipe it down with a degreaser / alcohol / acetone.

Regarding spray on undercoatings I have used the 3M Rubberized Undercoating (link) and its easy to use, but its only been a few years for me so I can't say how well it will hold up. IF you are currently rust free, you can just spray that over what you have now and skip the POR15.

I used this for rust conversion:

And this for the under body coating:

I used spray for both for getting into tight spaces. If I could do it again, I might line-x or monstaliner the underside for toughness though that coating was pretty tough it feels like it would scrape off on stuff but I sold my old 4runner before I could test that out.

I was looking into the below or Lizardskin. Still researching

That doesn't look too bad. But if you're not going to fix the issue (cut out those metal sections and replace them), since that's in the wheel well area which gets sprayed with water, sand from the road, etc.., I'd apply some undercoating on it to minimize the effects of road spray. 3M has a pretty good rubberized undercoating which I've used a few times (try not to touch it and wear some gloves) : https://www.amazon.com/gp/product/B002H9CMCQ/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

I guess the only issue is that it won't match the silver / gray of the vehicle.

3M Rubberized undercoat would be ideal for your purpose.

Smth like this one, can't remember the exact name but should work. Be sure to scrap the remainings of the old rubber texture and give it some sanding ! Good Luck !

Why not one of these? https://smile.amazon.com/3M-03584-Professional-Rubberized-Undercoating/dp/B002H9CMCQ

The same thought occurred to me. I wonder if something like this would work.

thanks for brainstorming this. may try this if no better option;

making a fitted cover over this is not an option - too much work.
