best rust proofing in a can?

[cudavid]

Hi To all,

I have a new 2014 Mazda 6, LOVE IT! BUT when I feel inner fender lips in back, seems like not much rust proofing and inner fender lip appears almost bare. Before inter, I want to pull the wheels and spray something around to starve off any rust issues.

What is the product of choice these days?

Thank you

Up here you can get Krown in spray cans. That's what I get. I don't know if you can get it there though.

Fluid Film works well for the same thing in our Fit's rear wheel wells. It does need yearly re-application.

You can skip NeverWet. It appears to only last a few minutes.

In the US its basically CarWell or FluidFilm. It seems CarWell lasts longer than FF or so I have read. Carwell you can get in aerosol cans or pump spray containers. CarWell is the same as Krown.

If it were me, I would make the trip to Dolgerville NY and have them spray it the first time for about $100. Its about 1 hour west of Albany. They will get it into the cavities that you will not be able to unless you have their equipment with 3 foot wands. And have some knowledge from doing a bunch of cars, trucks and school buses.

Then you can touch up the areas which get washed away over the year as they will not be in cavities and should be easy (if you have a lift.)

I have taken both my vehicles for the past 2 years. Yes a hassle, but worth it.

Are the areas in question subject to road-splash?

 

[cudavid]

yes I think they will, after running my hand around the junction of the inner fender(back) and the lip, I was uncomfortable with the gap and what I felt. The steel seems quite smooth, no evidence if any coating.

Another vote for Fluid Film.

I pretty much agree with the others here and I have done quite a bit of my own research on rust proofing.

I'm assuming you're replying to my question about whether the areas in question will be subject to road-splash.

If so, then Krown/Carwell will not help matters, since they will be washed off in the first rain. For high-impact areas that experience road-splash and sandblasting, more suitable would be a durable coating, such as the sort of substance they use for truck bed liners.

However, factory rust protection these days is so good, I don't think you need anything at all in those areas. Treating the interiors of the panels is more important, and that's where Carwell comes in.

I have used Coroless from Eastwood with very good results. Not sure though if they still sell it.

FF sticks around a bit, even when it appears to be washed off. The splash-prone areas on both cars still had water beading off surfaces for quite a while after running my fingers through the light coating of dust on them, even with no FF visible. I was impressed.

Thanks to all, I bought some LPS stuff thats like FF for some areas and 4 cans of 3 M rubberized undercoating for the wheel wells. I keep my cars for a long time, so I figure its a good investment.
