I've always done the same thing with linseed oil.

My father told me in the old days guys would bring home their new cars and put paper and sheets under them in the garage and open all the doors. They would then pour heavy motor oil down into all of the doors, coating the insides and just letting it drip out over the next 24 hours. It was the old hot-rodders way of keeping the doors from rusting out as water and rust could not adhere to a coat of oil. Not sure how long that would last...

I have always undercoated and rustproofed my vehicles and I've had very good luck, though I always keep them clean even in the winter. I even drilled tiny access holes in my Mazda door jams to spray in rust-proofing.

Drill holes into a unibody vehicle and it will be appraised as "frame damage" at time of sale, massively reducing its value. There's just no easy way on a computer made unibody frame to tell what parts are and aren't stressed since the whole body is the frame.

You have a decent warranty against rust, so I wouldn't bother with these as I can only see it creating warranty concerns.

Do you know this to be a fact or are you assuming? Krown states that all manufacturers have signed off that their process does not create warranty concerns. I was thinking of getting it done as soon as pick up my vehicle but I’m on the fence.

Fact. If Krown got manufacturers to sign off, then for unibody vehicles they must not be doing what they are doing to this 1960s car video and drilling holes. Maybe they are just using existing ports or removing some components to spray in instead of getting drill happy.

Interesting. Not trying to argue, but Krown says otherwise (and they do drill holes). I guess only someone from Ford can give a final answer.

I wouldn't trust Krown, and I wouldn't let anyone drill holes in my modern unibody vehicle, unless they just mean in doors or something which isn't actually "the frame". Still, modern vehicles are already built with great rust proofing, and while you'd think that putting icky goop everywhere can only help, who knows what weep holes the engineers designed that will end up getting clogged with this stuff.

There's also those things where people quote magnuson-moss in that the manufacturer has the burden of proof to show that the aftermarket modification caused the damage, but reality is that they simply say "nope, our tech thinks it caused the problem" and voila, you're black listed, and if you want to dispute it you have to hope the manf. takes your side over the dealer technician (not really inclined to) and otherwise you need a lawyer which most of the time isn't worth disputing. People went through this with Hyundai/Kia over using something as simple as an aftermarket oil filter... maybe not legal, but who has the time and money to fight it?

Same thing with Apple insisting you use Apple cables to charge their poop or they won't honor the warranty, not technically legal, but common anyway.

I'd let Ford fix any rust that happens in the first five years, if any, and then do aftermarket stuff when its no longer under warranty IMO.

The article says, if I remember correctly, that the hole drilling is optional. Just don't choose that option. If I lived in a state where I had to worry about rust that is what I would do. I agree with @JASmith, no extra holes in the unibody.

It's weird to me that this seems like a new tech or something on this forum.. In Canada, almost everyone I know Krown's their cars annually. This company has been around for decades around here. We have so much salt on our roads that this stuff is a godsend for rust, it even stops new rust from starting when you Krown an older vehicle. Krown guarantees the bottom 2' of your body panels if you got it done within the first month of owning a new vehicle.

A lot of dealerships will actually offer to get your vehicle Krowned before pick up. I doubt it would cause warranty issues..

In my opinion, new vehicles are NOT built with rust prevention in mind. In Pa, you better rustproof And drill holes if you want your vehicle to last. To hell with the mfg warranty, they don't care. I do. Mike.

Just picked up a case of Cosmoline 342. I'm going to spray everything I can get at with it. I will also take it to Ziebart for there oil coating. I think its better then Krown. I was all against drilling but now feel its worth it. Fill up all the rockers with anti rust coating. Lots of salt get put on canada roads.

I bought at 2011 Kia Soul to drive until I get the Maverick. It's been oil treated with 'Krown' yearly since new (records came with car). There is NO signs of any rust on the car, bottom of doors, wheel arches. This has sold me on getting the Maverick done by Krown.
Yes, they use a lot of rock salt on our roads in winter.Ken

I see you live in Texas. I have lived in Wisconsin for 69 years and believe me, if you are planning on keeping your vehicle more than five years, you better do something to protect it or it will cost you dearly. Once the rust starts there is nothing that stops it. You can only try to slow it down.

My Two cents, What I did with my 19 ranger was use the factory wheep holes and spray it with Fluid Film Using this will keep the warranty and still protect the rockers. The way I see it is that if the doors rust out after 12 years then they prolly has some dents as well there will be new door skins to bolt on if you wanna keep it. the biggest thing with the north is spray that fluid film and keep the wheep holes nice and clear and you will be in good shape !
