I am getting back into Mopars after some time off. I went and looked at a car last night and it had some critters living in the trunk. I am quite sure they have been doing unmentionable things in the lower quarters!
No through rust on the outside and they feel solid. Not much room down there.
Is there a product that I can spray in there from the trunkside to slow things down? I have used POR in the past and I will likely just get a long brush but I thought I would ask.
The car is an A body Duster. I live in the desert and things look ok, but I want to stop anything without removing steel etc. obviously.
Thank you for your help.

OK. I literally found live critters in there. I used to own the car years ago and it was about 99% free of rust, it is now 95%! It is actually in the narrow crack between the extension and the quarter on the inside.
Living where I do rust isn't a massive issue. But I would like to do something to stop it. I have the POR on hand and already or soon to be opened for another project.

I'm sure you know but, make sure you get rid of all the debris that the current residents have left in there. Personally I like the "Just dump used motor oil in there." idea.
I have mechanical Aptitude. I can screw up anything.

What are the chances that used oil out of an engine would have moisture in it that was acidic? I think I'd use fresh oil instead of used.

This is actually pretty interesting. That's why I am asking. I will definitely be giving the car a serious bath as it really needs it and the critters need to go.
Hadn't thought of the oil thing. Stuff generally does not rust here. And I know that POR has somewhat of a controversial rep, although I don't know why it wouldn't be appropriate.
Why would it be a bad idea to clean it as thoroughly as possible, and then get a long, think brush and apply POR or a very similar product? I'm basically talking about floor level and below on the lower quarter.

I swear by the Krown stuff. Used it when I lived in North Dakota on all my daily drivers and still do. You can get it in a spray can or some cities up north have guys that will apply it. Stays fluid instead of drying and fills all the areas that water (or mouse piss) would normally flow to. IMO it also helps keep existing corrosion from spreading as fast.

POR, if you can get it to actually stick, only serves as a barrier, trapping air, moisture and rust up against your sheet metal.

If oils ( engine or transmision ) didn't trap dust untill clogs everything would be great idea, but they ending causing a diff problem when saving the other one.
