Anybody in the north treat for rust?

[CountryBoy19]

The rubberized undercoat on my '05 is peeling off. I know it's trapping moisture and garbage. I'm thinking about getting it up on a rack or something and getting the underside pressure-washed/steam-cleaned then treating with a wax/oil based rust preventer like Fluid Film's lanolin based undercoat.

Thoughts?

I use fluidfilm. Have a friend with a lift at his house, so it’s easy. I also spray the door/fender/hood area, take out the taillights, and spray all that down as well.
Remove the plastic door sills, and spray inside the holes.
Lower inner fenders hit. Too, just have to move that material that’s there out of the way. I try to soak as much as I can, get into as many small spots too.

Does it help -- do you have rust?

I bought it in August. It already has some surface rust, floors are great. Just some scale here and there.
Trying to prevent as much as I can.

Nah, it's cool. I wasn't questioning you. I've just lived in the South all my life, and I was curious as to whether the treatments really worked or not, and what level of success you achieved. I've also read that GM used some very rust-prone metal in the years of our vehicles, so I was fishing for anyone having real rust issues (I, too, have surface rust, but nothing serious; my truck came from Oregon).

Thanks!

IMHO, all of them (auto makers) use really rust prone metals... rust is the nature of living in the rust belt...

Once the roads dry off after a salty snowstorm I get my ass over to the car wash for an over & undercarriage wash. Keeping it clean is the best defense.

We live in southern coastal Maine but we still get snow and they use a lot of salt on the roads.
We have a '16 Tahoe that we bought new in October '16 I run snows on it and after the first winter (the Tahoe was 6 months old!) when I was changing the snows, I noticed a LOT of surface rust on the frame. The dealer wouldn't do anything about it as it hadn't rusted through. I took it to a Ziebart dealer in Biddeford Maine and had them power wash it, spray it all with rust eliminator and then undercoat it. Cost was $700 but has been through a winter and a half since then and there is no sign of rust so I am pleased. (I also take it to a car wash at least weekly and have the bottom washed too. We have a great deal up here-unlimited car washes for $15/month!)

That's an awesome deal.

Bought my 03 Escalade in Vegas, and brought it up here to Western, PA two years ago. First act was to have a good coating of Fluid Film. No rust issues yet, but there are a few side effects to bare in mind. You will get a slight smell from it burning off the exhaust; brakes will fade slightly for the first mile, and the film will migrate up to the outside of the body for a while. These are not insurmountable problems, but Fluid Film does have its' share of side effects. My body shop charges $135.00 for the first application, and $117.00 every year there after. Wife's car was only $85.00.

New place just popped up by work. Unlimited for $17/mo. Been seriously considering it.

If your in the North, its better to just embrace it....

I'm starting to see a little rust in my lower rockers.

I treat my Yukon myself. Lots of salt on Michigan roads. I spray 5W20 motor oil everywhere I can get to on the underside, then drill all the doors and panels to spray oil into them. The wholes are then plugged with body plugs. Been doing all my cars for years that way. Still get surface rust on frame ans suspension parts but no other or serious rust. I use a low pressure high volume media blaster/sprayer from harbor freight. Then add an undercoating wand for going all the way inside doors and panels.

After this winter I will have to do some work on the undercarriage. IN the last year few years it started to get out of hand. Going to grab a wire brush to the frame and the use some rust inhibitor like naval jelly and then finish it off with something like eastwood encapsulator.

Naval jelly is not an inhibitor, it's an acidic converter. Putting it on your frame and leaving it could cause more harm than good. Don't the instructions say to remove it after it has converted the rust?

 

[ladorn45]

Yea i was not going to leave it on. I would apply it let it soak for how ever long it needs to in order to convert the rust and then rinse it off. After that i would add the eastwood.

That's the typical NJ undercarriage right there.

Ah, ok, that makes sense...

A little too much effort for my liking but if you have the time go for it!!! IIRC, you can get the same active ingredient as naval jelly in a liquid form (forget what it's called) that will spray on, but the you have to clean really good because it gets down in crevices etc and that gets really hard to get it all out before it starts doing bad things...

 

[ladorn45]

Yea ospho is another product that does it that is liquid form. There is also products that turn rust into iron like the below but i think you have to remove as much rust as possible
