Looking at just getting the essentials done before our winter hits here in Ontario.
Hard fold oem tonneau... Check
Rhino or linex spray in liner hopefully done this week.
Work schedule and weather is not cooperating but would like to get a coat of wax on before the snow flies.
How many of you rust proof and what company do you use?
I'm going to wait until the spring when I can do the adons myself like well liners, fender flares and mud flaps but would like to get as much protection as I can on the truck.

 

As a mechanic I don't like undercoating or rustproofing.
Nasty sticky gooey mess ....But it works. lol
I found a product a few yrs ago that this guy swore by !!
So I purchased some and used it regularly on my salter.
3yrs later the salter still looked new....

My f-150 only has 450 miles so far.
Just have to decide if I'm going to paint 1st or just spray this on.

 

I'm in the same boat. Can't decide if I should go ziebart or krown. Ziebart is $250 for the undercarriage, yearly touch up is $35. Krown is $140 for the full treatment, they won't do just the undercarriage, and have to get it done yearly. Also ziebart would do the rhino liner for $300 if I get the undercoating there, but I was leaning toward line x. 🤔

 

I would think with these trucks, DIY with a can or 2 of fluid film or similar should be sufficient. With all the aluminum (bottom of the cab, wheel wells, etc), even if that stuff were to start corroding eventually, it will still far outlive the truck before eating thru, likely just remaining a white powdery (oxide) dull surface. The e-coated frame theoretically should be good for life, barring chips and all, but even being prudent/skeptical on that aspect, should hold up several years before degrading. That pretty much just leaves hardware and the handful of other exposed bits like bolts, u-joints, shock studs, etc. Should be good for awhile just hitting that stuff, with maybe having to branch out to coating degraded areas of the frame and such as the truck ages.

 

Get it undercoated. You will hear lots of people saying the truck is aluminum and you don't need to... Aluminum still corrodes. And honestly even on a steel body truck, the things like brake and fuel lines will rot off before the body will rust out. Bolts seized to the point where you need a torch to unbolt anything = no fun.
I had my truck done with Krown as soon as I bought it, it's due to be sprayed again. Had my Previous truck done, and it looked like new when I traded it. Had a Silverado before that, didn't have it undercoated,the body looked great, but the brake and fuel lines needed replacing. Had a brand new Ford Ranger in 2006, didn't have that done either and when I got rid of that in 2009 for my Silverado, the bottoms of the doors were rusty.
I don't know if you do any work on your own vehicles, I'm a licensed mechanic, so I wrench on my own. It's nice when stuff unbolts lol.

 

Waste of money.

 

Depends on how long you want to own your truck. 3 years? Forget it. Keeping it for years? Money well spent - what a max $150.00 investment on a 45K truck? I prefer Corrosion Free. Just don't get it applied by Canadian Tire. Try to find an independent garage. Regardless of the product (huge migraine inducing debates for Krown vs Corrosion Free) it is all in the application. CF is very easy to DIY. TSC stores often carry it at 50% off at 5.00 a spray can. Probably 4 cans to do your entire truck. At that price and 20 minutes of your time, why not.

 

I have never gotten a vehicle undercoated. I've always been under the assumption it's snake oil. If it truly works, then why wouldn't the OEMs apply it from the factory?

 

Because they want to sell you another one !

 

When I bought my truck in 2013 I traded in my 15 year old Explorer. Bought in SE PA, heavily salted area, finished in Michigan, also heavily salted area. No rust that caused any issue.
