Picked up my truck yesterday. I'm happy with the rubberized undercoating. Seems very durable and will protect the wheel wells from rocks and debris. They missed some spots though, I have to go back

 

Where i live near cleveland they use brine on the roads in excess salt and sort of molasses mix, oil coating doesnt stand a chance i have replaced over 1000 feet of fuel line and brake line this year alone nasty stuff , cars look worse than they did 30 years ago and the dealers are still telling people rustproofing is bad for your car. You need it more than ever now.

 

Yeah, for sure.

For 20 or 30 years I been hearing people say things like "cars today don't need rustproofing" and I think yeah OK, you all do what you want Hoss but I'm getting mine rustproofed.

 

When is Krown coming to the US?

I like that it's like a mist and not oily.

 

OK, so correct if I am wrong but the new trucks come with a 100,000 mile rust warranty without requiring dealer or aftermarket "extra" rust proofing.

Just wish we could all get "the right answer on this". I am not opposed to having my new 2011 undercoated but also don't like the overspray and mess often caused, spots that are missed, and holes drilled, etc.

If this was "necessary" why isn't there a "requirement" to do so? Or your warranty is invalidated.

Or, is it just a matter of trying to "prevent surface rust" [likely over time even with galvanized hot dipped frame and sheet metal] vs. "rust through" [not likely]? Or just in the case you want to keep the truck for many many years beyond warranty which I will certainly do if it behaves or until they finally get 30mpg TDI clean diesel or something I want more.

 

It's to prevent this...

 

The Krown dealer I go to told me that they have been looking at opening up some locations in the US, but there is a trademark issue with the name Krown. They'd have to call it something else apparently.

Just to clarify, Krown is an oily product. The closest thing I can compare it to is WD-40 in terms of appearance, viscosity, and lubricating properties.

The misting occurs when they spray it. The oily stuff hits the surface, but a mist or fog of it forms and hangs in the air like a cloud. You should see their shops, there is not a spot of rust on ANYTHING in the shop because of this cloud. LOL.

 

So just to clarify, there arent any places in the US we can get a krown type application done?

 

I have lived in ohio for 47 years worked at ziebart while in college good product. I have been a mechanic for 28 years owned my own shop for 10 years and have seen it all, oil is great and i used to spray all my cars with p/s fluid every year underneath doors etc. Problem is it doesnt hold up like chemical coatings do, i have never seen rubber rustproofing cause any problems unless it has been applied incorrectly inside of doors covering window guides, tracks and drains never i mean never any problems underneath the vehicle. I just started appling it because i see a huge need in my area for it, all the places that used to aplly it closed up about 10 years ago.

 

I second that using oil to spray on the under carriage works great
