Stopping/eliminating rust

[Grandnat6]

I'm in need of some professonal advice.

I look under my car and see that half of the undercoating on the floor pan and frame is gone and my car is rusting. How do I fix this problem? Can I just take it to a Ziebart place and have them re-undercoat it? I'm afraid if I did that, it would continue to rust in between the new undercoating and the carpeting. I also see a spot in the trunk by the wheel well where it looks as if the rust is bubbling under the undercoat. My engine compartment is ok but is showing signs of rust as well. What should I do, I don't want my car to slowly rust away!

I'd get the car on a rack, strip off the Ziebart undercoating, sand it, and paint the undercarriage with POR-15. Great stuff.

I used POR-15 paint and putty to seal up my floor and trunk after fixing some rust spots. The stuff is a lifesaver. You don't even have to get rid of all the rust to seal it. You get rid of the loose stuff, and use a three part system to prep and paint it. As the paint cures, it removes the oxygen from the surface of the metal, and eliminates the possibility of rust coming back. The paint also bonds to the metal and actually strengthens weaker sections. It's not the same as welding in patch panels, but if you don't have large holes, you can use their fiberglass mesh with the paint and it's good as new. Well worth the money, IMO.

I've used POR-15 on a car once before. I wasn't able to keep the car long enough to find out if it really worked. I did see some rust bubbling under the POR-15 and had to redo it twice. I have mixed feeling about it. I was hopping to go with something better. I guess I would give it a try again. I don't know much about this, but how did you guys get it in the rocker panels?

Do you think people suspect a rust problem has been covered up when they see POR 15?

yes
thats why i take lots of pictures after sand-blasting

The POR 15 is ok but you may need to reapply it or Really do a good job on the prep.
I have used POR-15 on my wifes prior caravan's oil pan. seems the side that faces the front takes a lot abuse from road dirt. It started rusting so I applied POR 15 & noticed it held good for about 1 year. Had to redo it. Heck for what the Por 15 cost I could have put a NEW PAN in.

I would say Sand blast and replace any area with floor pans in your case.

Prep is everything. It's like painting anything else, if it isn't prepped right, it won't last. I've seen POR-15 on floor pans that's lasted 8 years so far.

SO TRUE on prep, But you don't live in the great Nor-SALT-EAST which can bring por 15 to its knees. :frown:

my street still has traces of winter sand on it. Suks up here for nice cars

Eastwood has a similar product, but they claim it is far better and lasts much longer than POR-15.

I woul get the undercoating off ASAP. My experience with undercoating is that allows someplace for moisture to accumulate and rusts what is underneath. You just do not see it. The frame on my Isuzu Rodeo is a mess. The undercoating started to flake off and I started removing it and the whole frame is rusty.

I'm not a pro but I have used a rust converter made by Klean Strip (don't know who they are) that works fairly well & is less expensive than the big name brands. It's a liquid that brushes on & chemically reacts with rust so you can paint over it without excessive sanding. Sold in Walmart, Advance, etc. Comes in small 16oz plastic bottles. They also sell a spray-on but that's no good.

Have used Por15 in the past without much success-:(

Also Have used Eastwood Rust Encapsulator www.eastwood.com- with better results.

both cost about the same.

just my 2cents :)

Anyone familiar or install some sort of electronic rust protection system?
Its a new gadget up here. See counteractrust.com. Its about $200. Im using rust check and have a rust spot thats the size of a nickel that hasn't gotten any bigger in 7 years. Under the car the stuff crawls into the nooks and crannies. And it smells nice.

I really like the Eastwood stuff. I have used it throughout the underside of my car with great results. No prep, just sprayed it on. I used the qt. can and a brush to do the hard-to-reach parts.

POR-15 works great if you put it on real thick. But only on spots you won't see (under the car, etc.)!
