Can any of you in the salt belt recommend a product for a DIY undercarriage coating?

Have you ever done this? How did you apply it?

With the salt & '5 nasty lines' season approaching, (pre-treatment they put on our roads here for you southern people), I'd like to coat the underside of my truck. Not too crazy about passing it off to someone to do, it's expensive, & the nearest place it 60 miles away. Looking for some advice & product recommendation from you knowledgeable folks. Thanks.

I just did mine last week, it will take you 10 cans, a throwaway tshirt, a couple pairs of gloves, a cheap pair of safety glasses, a little box of doctors office exam gloves and 1 hour of your time and 1 night to dry, I went to home Depot and picked up a bunch of rust oleum spray on rubbercoating, which is the same stuff I used when we did that at the chevrolet dealer and did pretty much my whole undercarriage. Once you start there's no stopping you. You should have it all done for under $50 and youl have better pride knowing it was done better than anyone else. And ups driver it's really something you'll be able to handle. It made a big difference already in road noise and to me it dosnt look like much was even painted at all. It really needs 2 coats, but I'll just redo it again next year and it will turn out even better

I appreciate the info Shawn. I've thought about using the rubberized coating before. Might go that route.

It's the same stuff we used at the dealerships but just in a consumer grade. The stuff we used was like tar in this quart bottle and we used paint thinner to cut it. So what you buy yourself is actually better. That's why when you get it done at the dealer it completely disappears in the couple years.

Hmmm. I'll take a look, thank you. I was unaware of POR making anything but a rust stop product.

Guys check this out,had it done last fall and plan on having it done yearly.
Approved by the military for rust prevention and it only cost around $100.00 to get it done.The only drawback is I had to drive several hours to get to their location which is near Buffalo N.Y.
The stuff reminded me of tranny fluid and they spray it EVERYWHERE.

The undercoating I got from the dealer seems to be applied pretty liberally it looks decent under there.

The package was lifetime warranty on rust/corrosion. I'm in Minnesota, rust happens and you can't stop it. But I figured it was worth the 1000$ to stick it to the dealer 6-8 years down the road when it does start to rust.

Because ultimately it will.

Went ahead and ordered a 2 gallon Fluid Film kit. Supposedly enough for mine and a buddie's truck. I upgraded the spray gun and added a 24" flexible extension wand. Came to about $175 shipped. So for $87.50, I should be covered for the season. Small price to pay for corrosion prevention here in the Rust Belt. I'll update this thread after application.

Well I got it done today. 1 gallon was enough for my EcoD and a friends '11 CCSB 2500 Hemi. Took about 3 hours total to do. Very satisfied with the product so far. Time will be the real teller.

I used my friends lift to get the truck in the air and just sprayed whole underside like I was painting a car. Then attached the flexible want to get inside the frame, over the wheel wells, and through the rocker panel access holes. And any other area I couldn't get with just the gun. Also used the aerosol can on the tailgate hinges, along bottom of bed side, and the trailer pin connectors.

I have a friend with a lift.. that is a life saver .. Living in IL rust and salt go together so you info came at the right time.. I was actuall having a conversation about the underneath of truck today.. and wanting to get it up on the lift and clean it.. to help keep it looking new.. My friend thinks I am nuts because I dust it every day and once a week open the hood and wash or dust what ever is needed in there to.. but getting underneath the truck is hard for me.. I have metal joints in both hips and knees and one ankle I don't like having to get on the ground..

The undercarriage looks pretty well protected from the factory. But as you know, one winter and its toast. Be warned tho, this stuff doesn't dry. It'll stay shiny and wet for a long time. Will collect some dust. It's ok tho because it's protecting your investment.
