Are 2014, and 2015 mazda3 rust resistance compare to Gen 1 and 2

[HYPER GEAR]

How are 2014, and 2015 mazda3 for rust? Mazda canada rust warranty is 7 years/unlimited km? Are they are the same as the older ones?

[Mr Wilson]

Hard to say this early. The first batch of gt sedans made in Japan have had some reports of rust in on spot welds in the trunk. Mexico cars so far seem good.

[Squisher]

I will point out that my white 15 gt from Japan with 14k and one winter under its belt has no such rusting.

I have a '14 Sport GS made in Mexico and just found a rust spot when i took off the read license plate to put a cover in. Will show dealer soon.

Jury is still out but rustproofing every year would seem to be a wise investment.

That's not going to do a thing about perforation rust, where the car rusts from the inside out. I think that's what most people are worried about, at least until the car is > 10-15 years old. Rust proofing is honestly a huge waste of money unless you're keeping your car a very long time.

They drill holes to spray the rust proofing inside body panels/doors/etc.

That's your opinion.

Every car I'll own will be rust proofed. I've seen just how effective it is on my Dakota.

I will agree some cars are much more resistant to rust than others. And m_bisson is right... Places like Krown will drill and spray an oil based film inside the common rust spots like rockers and doors.

Just had my 6th Krown application and the underbody is virtually rust free and zero rust around the other body areas. My alignment shop (Pat @ Altech) loves my cars because nothing is seized and a breeze to adjust. And when it comes time to replacing the suspension, Jimmy will not be killing himself removing seized mounts and components. Krown is certainly worth it in my books...

Your opinion. I disagree with it.

My 2008 3 was 4.5 years old when I bought it. Rust had already started when I bought it. It was Never rust proofed until I owned it. I had it sprayed and drilled. The underside is pretty bad and body rust is starting on multiple panels now.

My dad owned a 2000 Mazda protégé and rust proofed it at Krown from day 1: sprayed and drilled. Absolutely No body rust, very very minimal rust underneath the car when he sold it in 2011.

How long do you intend on keeping your Mazda, driven in Canada, un-rustproofed?

Going to keep the new car (2015) for at least 5 years and then sell. What should I do? Undercoat? Rust proof? or both of these things?

[stock3]

On a Mazda rustproofing is key if one wants to keep the car long time, 10 + years and have it not looking like a falling apart POS.
I've been rust proofing my 06 since brand new every year for the first 5 years and every other year after that.

Here is what it looked like last year. It was rustproofed one year before that.

Here is this year shortly after it was coated.

Said from some small spots on the suspension and cross members, there is no rust.
Now, despite all my efforts, which are probably more than the majority of car owners out there, the third brake light and the driver's side B pillar still started to rust. If this car wasn't rustproofed it would've looked like swiss cheese by now. I do love this car, but the quality of the body panels is shit.

Anybody that want to keep their Mazda for a long time, please start spraying it as soon as you get the car.

I would have it sprayed at Krown with holes drilled & then resprayed each season. The absence of rust 5 years from now and the fact that it was done consistently will help your resale value.

What about rust proof it at dealer with 10 year warranty (the price is right) and then undercoat regularly. This way no holes drilled. Wouldn't it yield the same result after 5 years as krowning it every year?

If the price is right and it comes with a warranty then go for it.
I don't know too much about it but find out their conditions on the warranty, that will help resale for sure. I think if you miss a spray one year then your warranty is toast. Don't quote me on that :P
Best call your dealer and inquire.

Thanks! Dealer says check ups are not required but you can schedule them any time on your own merit. 10 year warranty is solid no matter what. I am more interested if this warranty is against perforation or any kind of rust whatsoever, and whether or not 3rd party undercoating affects their (dealer's) warranty in any way. I used to do my undercoating at Mr. Lube. I guess I'll get in touch with dealer on that.

Just don't buy that electric rust proofing junk. I still firmly believe that an annual oil-based (Krown) or wax-based (fluid film) is best.

Nothing will ever be 100 % effective at stopping some sort of rust, but I guarantee not doing any sort of rust proofing will not last as long as something that is.

Yep, it's some sort of a spray'd on product that goes into inner cavities and crevices, not a module. Not sure what is an exact substance used, however.

[staax]

Symtech... I believe is what Mazda uses.

Good stuff, but needs to be reapplied after 6-7 years regardless of what the dealer says; at least from what my research has shown me.

Perhaps they use something else now I don't know. Krown is what I choose.

Good luck and enjoy the car!

My Dealer uses Platinum Shield package from First Canadian. I would choose Krown as well but there are few advantages of FC that I see right away:

1) same price
2) warranty is transferable
3) no holes
4) no check ups required

The only thing I am not sure of is the actual quality of their service. So, gotta do my research.
