I just purchased an 07 2500 quad cab. Should I have this thing undercoated/rust proofed or not?

 

Congrats on your new truck! Welcome to DTR!


If you go to "user cp" and fill in your signature that will help us help you, now and in the future with info on your truck etc. I don't know where you live, so I can't help with the undercoating/rustproofing question. I would think most likely not....but if you live where they spray salt on the roads.....then it sure couldn't hurt.

 

I did my truck and the wifes new GC. I feel it is cheap insurance to protect the truck. I also did them when they were only a day or so old.

 

Rust is usually NOT a issue on todays vehicles and hasn't been in many years.The products and companys that do it have grown smaller and less popular.The spay on stuff does help with some degree of sound deadening.The stuff that used to be installed with holes drilled and sprayed into areas caused more issues then it stopped.How many vehicles do YOU see with rust? Not like the old days for sure.I'd save my money for fuel etc.

 

ive found that you can buy bed liner spray at advanced auto for 6 bucks a can spray under truck it does a nice job makes cleaning under truck easy.you can also buy dupla-colors brush roll in stuff for 49.00 for a gallion it works great.

 

I would do it and have always done my trucks because I keep them longer then most . My 91's body is still in excellent shape because it was rust proofed and around here , in Ohio , a 91 with a no rust is hard to find . Down the road when you need to work on your truck you will also find the coated bolts will come out easily which is a nice added bonus . Sooner or later almost every truck will get into salt either by the ocean or in the snow and at there currant price I vote do it . I guess if I went out and got a new one every few years my opinion and the maintaining of it would be more conservative .

 

I had a 93W250.The metals used toady are a lot differant then in 93.Thats why the manufactures put such a long rust through warranty on vehicles today.I don't live coastal or in the snowbelts but I bet you see very few vehicles ate up with rust like yester years.When I was with Nissan they told us rust in islands/coastal was far greater the snowbelts states and they had been designing /working on that issue and about had to licked.That was in 98 or so.Most all manufactures were on the same page with this.

 

my thoughts exactly, save your money for fuel , or dressup items. the only thing i have the dealers ever do is mud flaps before it leaves the lot

 

Thanks for the input. I live on the coast near Vancouver Canada. It is interesting because the dealer recommends against undercoating, they say it can cause more problems than it solves. The biggest fear is that it cracks or separates somehow and holds the moisture and or salt in.

 

I would get it done. I still see alot of rust in my area. For the money that you put into the truck it would be worth it.

 

My memory is a bit vague on this but it seems that a few years ago this subject came up and it was mentioned that applying the undercoating could void the warranty on the body. I don't know if it is true or not but if so then would be something to consider.

 

i live in the rustbelt. i have had my truck sparayed each year for the last three years. my truck looks absolutely new underneath!!! this is the best stuff out there!!

You can save some money if you do it yourself, I mean, you can get the frame and whatever else you feel needs coating. Use Por-15. It's great stuff, can be rolled or brushed, it's super tough and once it's dried you can beat on it with a hammer and it won't come off.

 

i live in ohio, just traded my 01 ctd in for an 07 last week, it's already undercoated. The 01's doors were rusted through and every seam underneath the truck was beginning to bubble. The state road dept started spraying salt brine on the roads the day before a snow or freezing rain is expected, truckers all say that stuff is eating their trucks alive. I will never own another truck without undercoating it. The rust started in 04. That's my 2 cents...

 

Great info guys! I have decided to put something on the underside of my truck. Any strong preferences on which product is best? Question for rjm022... In Canada there are rust proofing dealers that go by the name "Krown" and I believe it is the same product that you are talking about. Did they have to drill any holes to spray this stuff in? Once it is done, does it drip onto your driveway or make any mess of your truck? One dealer that I talked with said that if you travel on a lot of gravel roads all the dirt will stick to the underside of the truck.
