I’m now living in North Africa and own a Kia Carens (insert Karen jokes here!) made in India. Overall seems like a fine car for what our options are but I’m dealing with quality issues as a 2023 with only 23k KM. I live close to the ocean and the sun is intense so I ceramic coated it when I bought it and its garage kept. I have some body and paint experience and can tell I’m running into issues however. The factory paint is thinner and the clear coat scratches easily. That’s not my focus on this post.

It was rusting at the fuel pocket where it meets the quarter panel. Warranty covered it. Jury out on quality of repair but it passed the eye test. I havent pulled the liner to check the backside of that repair. Recently the windshield washer pump got clogged. So while diagnosing that I pulled the fender liner to find this. Rusting at the seams in the wheel well. I’m guessing Kia is going to balk.

So…Process for stopping/treating the rust then sealing it? I’m likely going to have to do it myself with limited tools/access to brand specific products. Buying a car was such a process here it might honestly be less effort for myself to pull trim and wheelhouse liners and apply products etc than to deal with buying another car. May have to undercoat it too. My desire was to keep this car long term. But I’ll admit I am second guessing if it is in fact worth doing all this just to run into other quality concerns as it ages. Open to suggestions.

An old timer my dad bought a '68 Coupe De Ville from used to regularly wash it exclusively with a couple gallons of warm water with a cup of kerosene mixed into it. He would then wipe it dry with a soft cloth. The kerosene is oil based and stopped it from rusting at the seams. It also coated and protected the paint and trim work.

You can also spray it up under the undercarriage using a Hudson Sprayer to get all all those hard to reach places. It's cheap and it worked.
 

If it's all inner area's you could spray Rust Mort on it a few times until it's totally Black. Then rinse with water (Yes to neutralize) then let dry and paint and or undercoat it with a good tar base undercoat.Although this undercoat looks interesting and user friendly.

Those all look like good options. I’ll dig into them. Another friend suggested some Eastwood rust encapsulator. It comes in a spray can which would be good. The question with any of this is can I get it shipped here lol. Thank you guys I think I’m on a good track. Sorry I didn’t get the photos attached originally.
 
So I can’t import any type of paint. I’m basically stuck with what’s available here. I just looked underneath the car and there IS rubberized undercoating on probably 70% of the car. Where the floor pans overlap and are not undercoated have light rust like in the wheel well. There are a few drain holes open on the bottom as well.

My thought is I see what kind of rust prohibitor or sealer I can get here. Scuff those areas and spray it. And spray undercoating on top of that possibly.

Also since cavity wax stays tacky, I’m afraid to spray it into those drain holes as it will just make more dust stick to it. Or since dirt is likely already entering there should I not care?
 
Use the Eastwood rust encapsulator if you can get that. Old school method is brush roofing tar. Nice and thick. I restored a 1956 pick-up in the 70's. I wire wheeled, primed, painted, and then brushed with the tar. This can be brushed or sprayed. Mineral based so it can probably be thinned if needed.

I’m hoping to go to a body supply place next week. Some of our stuff is imported but basically I can’t import paint is what I’m learning.
